[the characteristics of the reproductive capacity of hybrids of banteng (bos (bibos) javanicus d'alton) with the domestic cow (bos (bos) primigenius taurus)].	the hybrid progeny of f1 produced by crossing of banteng and domestic cow is characterized by absolute sterility of the male line and fertility of the female line. the crossbred males become fertile in further progenies while crossing cross-females with males of initial forms. successful use of inter-subgenetic hybrids of banteng and domestic cow in selection work is hindered by pathological deviations in their genitals structure as well as frequent deaths of the embryos and foetus in hybrid cow ...	1992	1292161
prenatal growth and asymmetry of thyroid gland in the cattle (bos primigenius f. taurus).	growth and bilateral asymmetry of thyroid gland were studied in 291 fetuses (from 219 to 31,300 g) of the black-white cattle divided into 4 groups according to body weight. relation between body weight (x) and thyroid weight (y) was described using allometric equation y = axb. allometric coefficient b was different in each of the four groups (1.198; 1.179; 1.314; 0.941) and amounted to 1.076 for the entire fetal period. the coefficient of fluctuating asymmetry of the thyroid gland decreased with ...	1992	1339565
[expression of genes controlling modification of amylase in hybrids and original representatives of a cattle subfamily (bovinae)].	modifications of similar type were noted in the number of multiple amy-1 forms of amylase isozyme for various species of artiodactyla. it is supposed that these modifications are linked to periodical activation during evolution of genes responsible for modification of the molecules. data obtained on bovinae hybrids testify to this point of view. inactivation of active and reinactivation of "silent" genes responsible for modification of amy-1 molecules are observed in hybrids of bison x cow and b ...	1990	1706678
[an unusual case of chronic fibrosing endometritis and mucometra in a watusi cow (bos primigenius f. taurus) with uterine foreign bodies].	genital organs, ureter, urinary bladder, and blood were collected from a 12 year old watusi cow which never exhibited estrous behaviour. post-mortem findings and hormone assays, however, indicated the incidence of recent estrous cycles. the animal showed a chronic panmetritis, retained fetal membranes or fetal residues, an infected mucometra with cystic glandular hyperplasia, and a leiomyoma. tubular genitalia, ureter, and urinary bladder exhibited subacute inflammation.	1991	1914949
[the cytomorphology of goblet cells of the fetal intestine. studies of the large intestine of cattle (bos primigenius taurus)].	in the region of the base of the intestinal crypts undifferentiated goblet cells display a configuration and constellation of organelles and membrane structures that are indicative of their importance for function. these images at this stage of development deliver a scenario of the mechanism of secretory granule production: aggregates of protein vesicles from the "transitional elements" (palade) of the granular endoplasmic reticulum are, so to speak, rolled up on the trans side of the golgi appa ...	1990	2096533
[endocrine cells in the epithelium of the fetal large intestine of cattle (bos primigenius taurus) from the cytomorphological aspect].	in the epithelium of the fetal bovine large intestine there are endocrine cells, predominantly at the base of the crypts. according to morphological characteristics, ec-cells and l-cells can be readily distinguished.	1990	2403209

extensive mhc class ii drb3 diversity in african and european cattle.	genetic diversity at the highly polymorphic bola-drb3 locus was investigated by dna sequence analyses of 18 african cattle from two breeds representing the two subspecies of cattle, bos primigenius indicus and bos primigenius taurus. the polymorphism was compared with that found in a sample of 32 european cattle from four breeds, all classified as b. p. taurus. particularly extensive genetic diversity was found among african cattle, in which as many as 18 alleles were recognized in this small ra ...	1995	7590975
[the characteristics of the reproductive capacity of hybrids of the bison (bison bison l.) with the domestic cow (bos (bos) primigenius taurus). 1. the reproductive capacity of hybrid males].	the hybrid progeny f1 produced by intergeneric crosses of a bison with a domestic cow is characterized by absolute sterility of the male line and fertility of the female line. crossing of females with fertile males of initial forms permits us to obtain fertile males in the following generations. any differences in stabilization of spermatogenesis in hybrid males obtained from various crosses and under selection of parental couples were not detected.	1995	7676511
basic properties of the pyruvate dehydrogenase complex isolated from aurochs heart.	the purified aurochs (bison bonasus, european bison) heart pyruvate dehydrogenase complex (pdc) has a set of subunits typical of mammalian pdc. pdc from aurochs heart contains firmly bound tiamine pyrophosphate in the amount providing over 50% of the maximal activity of the complex. the apparent value for activation energy of pdc is 60 kj/mol. the michaelis constant values for aurochs heart pdc are 22.4 +/- 1.0, 3.3 +/- 0.1 and 24.4 +/- 3.6 microm for pyruvate, coa and nad, accordingly. acetyl-c ...	1994	7732764
[blood group polymorphism in bison (bison bonasus)].	polymorphism of nine blood group systems was studied in three reproductive lines of auroch (european bison bison bonasus), belovezhskaya, caucasian-belovezhskaya, and gornaya. all blood group systems analyzed were polymorphic; 50 out of the 57 antigens tested were detected. the number of detected blood group antigens in aurochs is comparable to that in breeds of domestic cattle. however, intrapopulation diversity, estimated with the mu test, is significantly higher in cattle than in aurochs. the ...	1995	7896131
evidence for two independent domestications of cattle.	the origin and taxonomic status of domesticated cattle are controversial. zebu and taurine breeds are differentiated primarily by the presence or absence of a hump and have been recognized as separate species (bos indicus and bos taurus). however, the most widely held view is that both types of cattle derive from a single domestication event 8000-10,000 years ago. we have examined mtdna sequences from representatives of six european (taurine) breeds, three indian (zebu) breeds, and four african ...	1994	8146187
some toxic and trace metals in big game hunted in the northern part of poland in 1987-1991.	game animal meats (muscle, liver and kidneys) collected from different regions in northern part of poland in 1987-1991 were analysed for mercury, cadmium, lead, copper, manganese, zinc and iron. toxic mercury, cadmium and lead occurred in relatively low concentrations in muscle and organ meats, with the exception of lead in muscle and cadmium in kidneys, which were relatively more contaminated. the concentrations of essential trace metals in samples examined seemed to be natural. roe-deer contai ...	1994	8178124
constitutive amplification of a zinc finger protein gene in cattle.	the human ozf gene encodes a protein consisting essentially of zinc finger motifs of the krüppel type. evolutionary studies revealed amplification of the bovine ozf gene in cattle. domestic cattle includes two major subspecies: taurine (bos primigenius taurus) and zebu (b. p. indicus). amplified sequences were found in both subspecies and mapped to the same locus of chromosome x in band q11. no amplification was found in other bovids and in particular in bison, the closest related genus to the g ...	1996	8561900
changes in some properties of the aurochs heart pyruvate dehydrogenase complex induced by its partial phosphorylation.	comparative studies on the properties of the dephosphorylated and partially phosphorylated (to 35% activity reduction) pyruvate dehydrogenase complex (pdc) from aurochs heart muscle have been made. data have been obtained indicating that the partial phosphorylation of pdc abolishes the kinetic attributes of a positive cooperativity of the pyruvate binding sites (nh = 1.5) featuring at low substrate concentrations. in addition, the partially phosphorylated pdc is inactivated slower at 50 degrees ...	1995	8592780
structure and topography of the nuclei of mamillary region in the bison bonasus.	studies were carried out on the brains of two aurochs. the paraffin cross-sections 15 microns thick were stained according to nissl and klüver and barrera methods. in regio mamillaris were described two mamillary nuclei and two paramamillary nuclei. nucleus mamillaris lateralis and nucleus supramamillaris are uniform cellular bands while the nucleus mamillaris medialis and nucleus tuberomamillaris pars posterior consist of subdivisions. thopography of these centers in aurochs is similar to other ...	1995	8606028
mitochondrial diversity and the origins of african and european cattle.	the nature of domestic cattle origins in africa are unclear as archaeological data are relatively sparse. the earliest domesticates were humpless, or bos taurus, in morphology and may have shared a common origin with the ancestors of european cattle in the near east. alternatively, local strains of the wild ox, the aurochs, may have been adopted by peoples in either continent either before or after cultural influence from the levant. this study examines mitochondrial dna displacement loop sequen ...	1996	8643540
an investigation of the kinase activity of aurochs heart pyruvate dehydrogenase complex.	the purified aurochs heart pyruvate dehydrogenase complex (pdc) saturated to approximation 60% with endogenous thiamine pyrophosphate (tpp), was slowly and incompletely inactivated by its kinase in the presence of atp. exogenous tpp or adp, but not pyruvate, strongly inhibited the kinase activity. the kinetic properties of the aurochs heart pdc kinase suggested the occurrence of two active sites each with different affinities for atp (k'm - 1.7 microm, k''m = 48 microm).	1995	8673014
the horizontal cells of artiodactyl retinae: a comparison with cajal's descriptions.	the morphology of horizontal cells in ox, sheep, and pig retinae as observed after lucifer yellow injections are described and compared with the descriptions of golgi-stained cells by ramón y cajal (1893). horizontal cells in the retinae of less domesticated species, wild pig, fallow and sika deer, mouflon, and aurochs were also examined. all these retinae have two types of horizontal cell; their morphologies are in common, although with some familial differences. their basic appearance is as ca ...	1996	8870229
ancient dna suggests a recent expansion of european cattle from a diverse wild progenitor species.	a total of 11 bos primigenius and bos taurus bones from archaeological sites between 500 and 12000 years old were examined for the presence of dna. it was possible to amplify and sequence mitochondrial control region dna extracted from seven of the 11 samples, including two pleistocene b. primigenius samples. we compared the results with published data by constructing phylogenetic networks. the two b. primigenius samples clustered with the extant b. taurus samples in the networks. the similarity ...	1996	8952089
[the characteristics of the reproductive capacity of hybrids of the bison (bison bison l.) with the domestic cow (bos (bos) primigenius taurus). the reproductive capacity of hybrid females].	reproduction ability of hybrid females received in various variants of absorbent and variable crossing of bison and domestic cow has been studied. normal development of genitals, oogenesis, display of sexual activity, as well as fertilization have been found in all females, independently of their blood content. frequent cases of "relative" sterility in some females of the i-iii generations have immunological character and are predominantly caused by the mortality of embryos and fetuses at variou ...	1997	9381557
mitochondrial dna variation and evolution of japanese black cattle (bos taurus).	this article describes complete mitochondrial dna displacement loop sequences from 32 japanese black cattle and the analysis of these data in conjunction with previously published sequences from african, european, and indian subjects. the origins of north east asian domesticated cattle are unclear. the earliest domestic cattle in the region were bos taurus and may have been domesticated from local wild cattle (aurochsen; b. primigenius), or perhaps had an origin in migrants from the early domest ...	1998	9799268
[early fetal development of the small intestine mucosa in cattle (bos primigenius taurus)].	the development of the bovine small intestine was examined in 24 embryos and fetuses by light microscopic, scanning and transmission electron microscopic methods. special reference was paid to the genesis of the epithelium and particularly of the villi intestinales. the primitive intestine consists of one layer of epithelial cells surrounded by mesenchym and tunica serosa. the fetal intestine (up to the 24th week of gestation) shows all the morphologic structures of the adult. in small intestine ...	1998	9818454
[prenatal development of the lamina epithelialis in the phase of vacuolization of villous epithelial cells. investigations on the intestines of cattle (bos primigenius taurus l., 1758)].	the development of the bovine small intestine was examined in 39 embryos and fetuses by light microscopic and transmission electron microscopic methods. special reference was paid to the histogenesis of the ephithelium. in contrast to the duodenum the epithelium of jejunum and ileum undergoes a degeneration by vacuolation of its villous epithelial cells. the demonstration of the acid phosphatase activity of these vacuoles shows their lysosomal character. this degenerative process of the small in ...	1998	9972643

genetic evidence for near-eastern origins of european cattle.	the limited ranges of the wild progenitors of many of the primary european domestic species point to their origins further east in anatolia or the fertile crescent. the wild ox (bos primigenius), however, ranged widely and it is unknown whether it was domesticated within europe as one feature of a local contribution to the farming economy. here we examine mitochondrial dna control-region sequence variation from 392 extant animals sampled from europe, africa and the near east, and compare this wi ...	2001	11323670
[the functional morphology of the large intestinal mucosa of the ox (bos primigenius f. taurus), sheep (ovis ammon f. aries) and goat (capra aegagrus f. hircus)].	the mucous membrane of the large intestine of the ox, sheep and goat was studied using light and electron microscopy. the surface epithelium possesses the well-known complement of organelles with a conspicuous number of mitochondria as a source of energy for absorptive activities. occasionally, brush cells are found in the epithelium; the functional significance of this type of cell is still under discussion. in the present material, electron-lucid spheroids (diameter: 45 x 35 nm), which tend to ...	2001	11379368
the effect of lactic acid on odour-related host preference of yellow fever mosquitoes.	in a behavioural study we have investigated the role of lactic acid for the host preferences of yellow fever mosquitoes (aedes aegypti) by comparing the attractiveness of rubbings from the hands of different human individuals and extracts obtained from skin rubbings from different mammals (bos primigenius f. taurus, capra aegagrus f. hircus, felis silvestris f. catus and homo sapiens). certain human individuals were consistently more attractive to mosquitoes than others. addition of lactic acid ...	2001	11418498
healthy skin of many animal species harbors papillomaviruses which are closely related to their human counterparts.	papillomaviruses associated with clinical symptoms have been found in many vertebrate species. in this study, we have used an l1 gene consensus pcr test designed to detect a broad spectrum of human skin papillomaviruses to analyze swab samples from healthy skin of 111 animals belonging to 19 vertebrate species. in eight of the species, papillomavirus dna was found with the following prevalences: chimpanzees, 9 of 11 samples positive; gorillas, 3 of 4; long-tailed macaques, 14 of 16; spider monke ...	2002	12438579
heteroplasmy in bovine fetuses produced by intra- and inter-subspecific somatic cell nuclear transfer: neutral segregation of nuclear donor mitochondrial dna in various tissues and evidence for recipient cow mitochondria in fetal blood.	varying degrees of mitochondrial dna (mtdna) heteroplasmy have been observed in nuclear transfer embryos, fetuses, and offspring, but the mechanisms leading to this condition are unknown. we have generated a clone of 12 bovine somatic cell nuclear transfer fetuses, using nuclear donor cells, recipient oocytes, and recipient heifers with defined mtdna genotypes, to study nuclear-mitochondrial interactions and the origins of mtdna heteroplasmy. embryos were reconstructed from granulosa cells with ...	2003	12493708
independent mitochondrial origin and historical genetic differentiation in north eastern asian cattle.	in order to clarify the origin and genetic diversity of cattle in north eastern asia, this study examined mitochondrial displacement loop sequence variation and frequencies of bos taurus and bos indicus y chromosome haplotypes in japanese, mongolian, and korean native cattle. in mitochondrial analyses, 20% of mongolian cattle carried b. indicus mitochondrial haplotypes, but japanese and korean cattle carried only b. taurus haplotypes. in contrast, all samples revealed b. taurus y chromosome hapl ...	2004	15223036
variability and evolution of bovine beta-defensin genes.	defensins comprise an important family of antimicrobial peptides. among vertebrates numerous defensin genes have been detected, but their evolutionary background is still discussed. we investigated the molecular evolution of bovine defensins via screening of different bovine species including the extinct ancestor of domestic cattle (bos primigenius) for beta-defensin encoding genes. we detected a large variability of new defensin encoding sequences similar to previously published bovine neutroph ...	2005	15674371
prehistoric contacts over the straits of gibraltar indicated by genetic analysis of iberian bronze age cattle.	the geographic situation of the iberian peninsula makes it a natural link between europe and north africa. however, it is a matter of debate to what extent african influences via the straits gibraltar have affected iberia's prehistoric development. because early african pastoralist communities were dedicated to cattle breeding, a possible means to detect prehistoric african-iberian contacts might be to analyze the origin of cattle breeds on the iberian peninsula. some contemporary iberian cattle ...	2005	15941827
close genetic relationship of early neolithic cattle from ziegelberg (freising, germany) with modern breeds.	in 2003 a variety of crafts and bone specimens were found during excavations of a neolithic settlement near freising, the southernmost site of the linear pottery culture in bavaria. six cattle bones were used to extract ancient dna (adna). applying nested and touchdown pcr, two fragments of the mitochondrial (mt) dna control region could be amplified from specimen 533/iii which yielded a total of 230 base pairs (bp). the sequence was compared with the homologous part of 40 extant breeds of bos t ...	2005	16130455
cattle domestication in the near east was followed by hybridization with aurochs bulls in europe.	domesticated cattle were one of the cornerstones of european neolithisation and are thought to have been introduced to europe from areas of aurochs domestication in the near east. this is consistent with mitochondrial dna (mtdna) data, where a clear separation exists between modern european cattle and ancient specimens of british aurochsen. however, we show that y chromosome haplotypes of north european cattle breeds are more similar to haplotypes from ancient specimens of european aurochsen, th ...	2005	16243693
the origin of european cattle: evidence from modern and ancient dna.	cattle domestication from wild aurochsen was among the most important innovations during the neolithic agricultural revolution. the available genetic and archaeological evidence points to at least two major sites of domestication in india and in the near east, where zebu and the taurine breeds would have emerged independently. under this hypothesis, all present-day european breeds would be descended from cattle domesticated in the near east and subsequently spread during the diffusion of herding ...	2006	16690747
evolution of bovine herpesvirus 4: recombination and transmission between african buffalo and cattle.	bovine herpesvirus 4 (bohv-4) has been isolated from cattle throughout the world, but virological and serological studies have suggested that the african buffalo is also a natural host for this virus. it has previously been found that the bo17 gene of bohv-4 was acquired from an ancestor of the african buffalo, probably around 1.5 million years ago. analysis of the variation of the bo17 gene sequence among bohv-4 strains suggested a relatively ancient transmission of bohv-4 from the buffalo to t ...	2006	16690915
polymorphisms of two y chromosome microsatellites in chinese cattle.	two y chromosome specific microsatellites umn2404 and umn0103 were genotyped and assessed for polymorphisms in a total of 423 unrelated males from 25 indigenous chinese cattle breeds. consistently, both microsatellites displayed specific indicine and taurine alleles in each bull examined. the indicine and taurine alleles were detected in 248 males (58.6%), and 175 males (41.4%), respectively, although these frequencies varied amongst different breeds examined. the indicine alleles dominated in t ...	2006	16954044
freshly excavated fossil bones are best for amplification of ancient dna.	despite the enormous potential of analyses of ancient dna for phylogeographic studies of past populations, the impact these analyses, most of which are performed with fossil samples from natural history museum collections, has been limited to some extent by the inefficient recovery of ancient genetic material. here we show that the standard storage conditions and/or treatments of fossil bones in these collections can be detrimental to dna survival. using a quantitative paleogenetic analysis of 2 ...	2007	17210911
[history and economic importance of cattle (bos taurus l.) in switzerland from neolithic to early middle ages].	in switzerland domestic cattle (bos primigenius f. taurus resp. bos taurus l.) first appear with the earliest neolithic settlements (approximately 5000 bc). with the gradual deforestation of the landscape caused by human exploitation of the environment, cattle were used more intensive and in many ways. there is evidence that cattle were used as draught animal since ca. 3400 bc, probably even earlier milk was regularly used. the size of domestic cattle gradually decreased from early neolithic unt ...	2007	17243447
mitochondrial dna analysis shows a near eastern neolithic origin for domestic cattle and no indication of domestication of european aurochs.	the extinct aurochs (bos primigenius primigenius) was a large type of cattle that ranged over almost the whole eurasian continent. the aurochs is the wild progenitor of modern cattle, but it is unclear whether european aurochs contributed to this process. to provide new insights into the demographic history of aurochs and domestic cattle, we have generated high-confidence mitochondrial dna sequences from 59 archaeological skeletal finds, which were attributed to wild european cattle populations ...	2007	17412685
modern hunting behavior in the early middle paleolithic: faunal remains from misliya cave, mount carmel, israel.	understanding the behavioral adaptations and subsistence strategies of middle paleolithic humans is critical in the debate over the evolution and manifestations of modern human behavior. the study of faunal remains plays a central role in this context. until now, the majority of levantine archaeofaunal evidence was derived from late middle paleolithic sites. the discovery of faunal remains from misliya cave, mount carmel, israel (>200 ka), allowed for detailed taphonomic and zooarchaeological an ...	2007	17669471
resolving a zoological mystery: the kouprey is a real species.	the kouprey is a rare and enigmatic forest ox discovered by scientists in cambodia only in 1937. numerous morphological hypotheses have been proposed for the origin of the kouprey: that it is a species closely related to banteng and gaur, two other wild oxen of southeast asia; a morphologically divergent species placed in a separate genus, named novibos; a wild species linked to aurochs and domestic cattle; a vicariant population of banteng; a feral cattle; or a hybrid of banteng with either zeb ...	2007	17848372
mitochondrial dna control region analysis of a late neolithic aurochs (bos primigenius boj. 1827) from the carpathian basin.	bos primigenius, the wild aurochs is believed to be the ancestor of european domestic cattle, bos taurus. the geography and climate of the great hungarian plain were well suited for these large grazing animals in the late neolithic. till now, there are just a few aurochs mtdna fragments available from two geographically restricted area, the british isles and italy. to increase our knowledge about the genetics of the european aurochsen livestock, and to investigate the phylogenetic position of a ...	2007	18297799

correlating bayesian date estimates with climatic events and domestication using a bovine case study.	the tribe bovini contains a number of commercially and culturally important species, such as cattle. understanding their evolutionary time scale is important for distinguishing between post-glacial and domestication-associated population expansions, but estimates of bovine divergence times have been hindered by a lack of reliable calibration points. we present a bayesian phylogenetic analysis of 481 mitochondrial d-loop sequences, including 228 radiocarbon-dated ancient dna sequences, using a mu ...	2008	18426745
complete mitochondrial genomes of bos taurus and bos indicus provide new insights into intra-species variation, taxonomy and domestication.	the taurine and zebuine cattle breeds comprise the majority of the world cattle population but their taxonomic status is still controversial. the two forms of cattle are currently classified as bos taurus and bos indicus species and are differentiated primarily by the presence or absence of a hump. however, these two species hybridize readily, producing fully fertile offspring. we have determined and analyzed complete b. taurus and b. indicus mitochondrial genome sequences to investigate the ext ...	2008	18467841
temporal fluctuations of y-chromosomal variation in bos taurus.	phylogeography has recently become more abundant in studies of demographic history of both wild and domestic species. a single nucleotide polymorphism (snp) in the intron of the y-chromosomal gene uty19 displays a north-south gradient in modern cattle. support for this geographical distribution of haplogroups has previously also been seen in ancient cattle from germany. however, when analysing 38 historic remains of domestic bulls and three aurochs from northern europe for this snp we found no s ...	2008	18713712
ancestral matrilineages and mitochondrial dna diversity of the lidia cattle breed.	to clarify the genetic ancestry and the mitochondrial dna (mtdna) diversity of the lidia cattle breed, a 521-bp d-loop fragment was sequenced in 527 animals belonging to 70 herds distributed across 29 lineages. the mtdna diversity recorded was similar to that seen for middle eastern breeds and greater than that recorded for the majority of european breeds. haplotype t3 was the most common (81%), followed by the african t1 haplotype (17%); very low frequencies were recorded for haplotypes t and t ...	2008	18822101
y chromosome haplotype analysis in portuguese cattle breeds using snps and strs.	dna samples from 307 males of 13 portuguese native cattle breeds, 57 males of the 3 major exotic breeds in portugal (charolais, friesian, and limousin), and 5 brahman (bos indicus) were tested for 5 single nucleotide polymorphisms, 1 "indel," and 7 microsatellites specific to the y chromosome. the 13 y-haplotypes defined included 3 previously described patrilines (y1, y2, and y3) and 10 new haplotypes within bos taurus. native cattle contained most of the diversity with 7 haplotypes (h2y1, h3y1, ...	2009	18832111
y-snps do not indicate hybridisation between european aurochs and domestic cattle.	previous genetic studies of modern and ancient mitochondrial dna have confirmed the near eastern origin of early european domestic cattle. however, these studies were not able to test whether hybridisation with male aurochs occurred post-domestication. to address this issue, götherström and colleagues (2005) investigated the frequencies of two y-chromosomal haplotypes in extant bulls. they found a significant influence of wild aurochs males on domestic populations thus challenging the common vie ...	2008	18852900
differences in fecal particle size between free-ranging and captive individuals of two browser species.	data from captive animals indicated that browsing (br) ruminants have larger fecal particles-indicative of lesser chewing efficiency-than grazers (gr). to answer whether this reflects fundamental differences between the animal groups, or different reactions of basically similar organisms to diets fed in captivity, we compared mean fecal particle size (mps) in a gr and a br ruminant (aurox bos primigenius taurus, giraffe giraffa camelopardalis) and a gr and a br hindgut fermenter (przewalski's ho ...	2008	19360605
distribution and extinction of ungulates during the holocene of the southern levant.	the southern levant (israel, palestinian authority and jordan) has been continuously and extensively populated by succeeding phases of human cultures for the past 15,000 years. the long human impact on the ancient landscape has had great ecological consequences, and has caused continuous and accelerating damage to the natural environment. the rich zooarchaeological data gathered at the area provide a unique opportunity to reconstruct spatial and temporal changes in wild species distribution, and ...	2009	19401760
cytochrome b sequences of ancient cattle and wild ox support phylogenetic complexity in the ancient and modern bovine populations.	mitochondrial dna has been the traditional marker for the study of animal domestication, as its high mutation rate allows for the accumulation of molecular diversity within the time frame of domestic history. additionally, it is exclusively maternally inherited and haplotypes become part of the domestic gene pool via actual capture of a female animal rather than by interbreeding with wild populations. initial studies of british aurochs identified a haplogroup, designated p, which was found to be ...	2009	19456314
the multifaceted origin of taurine cattle reflected by the mitochondrial genome.	a neolithic domestication of taurine cattle in the fertile crescent from local aurochsen (bos primigenius) is generally accepted, but a genetic contribution from european aurochsen has been proposed. here we performed a survey of a large number of taurine cattle mitochondrial dna (mtdna) control regions from numerous european breeds confirming the overall clustering within haplogroups (t1, t2 and t3) of near eastern ancestry, but also identifying eight mtdnas (1.3%) that did not fit in haplogrou ...	2009	19484124
differential passage of fluids and different-sized particles in fistulated oxen (bos primigenius f. taurus), muskoxen (ovibos moschatus), reindeer (rangifer tarandus) and moose (alces alces): rumen particle size discrimination is independent from contents stratification.	ruminant species differ in the degree that their rumen contents are stratified but are similar insofar that only very fine particles are passed from the forestomach to the lower digestive tract. we investigated the passage kinetics of fluid and particle markers (2, 10 and 20 mm) in fistulated cattle (bos primigenius f. taurus), muskoxen (ovibos moschatus), reindeer (rangifer tarandus) and moose (alces alces) on different diets. the distribution of dry matter in the rumen and the viscosity of rum ...	2010	19896552
pronounced segregation of donor mitochondria introduced by bovine ooplasmic transfer to the female germ-line.	ooplasmic transfer (ot) has been used in basic mouse research for studying the segregation of mtdna, as well as in human assisted reproduction for improving embryo development in cases of persistent developmental failure. using cattle as a large-animal model, we demonstrate that the moderate amount of mitochondria introduced by ot is transmitted to the offspring's oocytes; e.g., modifies the germ line. the donor mtdna was detectable in 25% and 65% of oocytes collected from two females. its high ...	2010	19955333
a complete mitochondrial genome sequence from a mesolithic wild aurochs (bos primigenius).	the derivation of domestic cattle from the extinct wild aurochs (bos primigenius) has been well-documented by archaeological and genetic studies. genetic studies point towards the neolithic near east as the centre of origin for bos taurus, with some lines of evidence suggesting possible, albeit rare, genetic contributions from locally domesticated wild aurochsen across eurasia. inferences from these investigations have been based largely on the analysis of partial mitochondrial dna sequences gen ...	2010	20174668
population dynamic of the extinct european aurochs: genetic evidence of a north-south differentiation pattern and no evidence of post-glacial expansion.	the aurochs (bos primigenius) was a large bovine that ranged over almost the entirety of the eurasian continent and north africa. it is the wild ancestor of the modern cattle (bos taurus), and went extinct in 1627 probably as a consequence of human hunting and the progressive reduction of its habitat. to investigate in detail the genetic history of this species and to compare the population dynamics in different european areas, we analysed bos primigenius remains from various sites across italy.	2010	20346116
necrotizing infiltrative lipomatosis in a miniature zebu bull (bos primigenius indicus).	lipomatosis is described in a miniature zebu, bos primigenius indicus, bull that died of perianesthetic complications. this is the first pathologic description of lipomatosis that we are aware of in this species and breed of cattle. infiltration of multiple visceral organs is described and depicted along with comparison to previously published cases of lipomatosis in other breeds of cattle.	2010	20445793
cattle demographic history modelled from autosomal sequence variation.	the phylogeography of cattle genetic variants has been extensively described and has informed the history of domestication. however, there remains a dearth of demographic models inferred from such data. here, we describe sequence diversity at 37 000 bp sampled from 17 genes in cattle from africa, europe and india. clearly distinct population histories are suggested between bos indicus and bos taurus, with the former displaying higher diversity statistics. we compare the unfolded site frequency s ...	2010	20643743
association of snps on capn1 and cast genes with tenderness in nellore cattle.	we examined whether single-nucleotide polymorphisms (snps) in the calpain (capn) and calpastatin (cast) genes, described from bos primigenius taurus, are polymorphic in nellore cattle. we also looked for a possible association of linkage disequilibrium of this polymorphism with tenderness of the longissimus dorsi muscle after 7, 14 and 21 days of postmortem aging in 638 purebred nellore bulls. meat tenderness was measured as warner-bratzler shear force. additive and dominance effects were tested ...	2010	20662159
insights into the genetic history of french cattle from dense snp data on 47 worldwide breeds.	modern cattle originate from populations of the wild extinct aurochs through a few domestication events which occurred about 8,000 years ago. newly domesticated populations subsequently spread worldwide following breeder migration routes. the resulting complex historical origins associated with both natural and artificial selection have led to the differentiation of numerous different cattle breeds displaying a broad phenotypic variety over a short period of time.	2010	20927341
tracing the biological origin of animal glues used in paintings through mitochondrial dna analysis.	we report the development of a suitable protocol for the identification of the biological origin of binding media on tiny samples from ancient paintings, by exploitation of the high specificity and high sensitivity offered by the state-of-the art dna analysis. in particular, our aim was to molecularly characterize mitochondrial regions of the animal species traditionally employed for obtaining glues. the model has been developed using aged painting models and then tested to analyze the organic c ...	2010	20953766
the effect of size and density on the mean retention time of particles in the reticulorumen of cattle ( bos primigenius f. taurus), muskoxen ( ovibos moschatus) and moose ( alces alces).	particle passage from the reticulorumen (rr) depends on particle density and size. forage particle density and size are related and change over time in the rr. particle density mainly influences sorting in the reticulum, whereas particle size influences particle retention in the fibre mat of stratified rumen contents ('filter-bed' effect). we investigated these effects independently, by inserting plastic particles of different sizes (1, 10 and 20 mm) and densities (1·03, 1·20 and 1·44 mg/ml) in ...	2010	21144130
the enigmatic origin of bovine mtdna haplogroup r: sporadic interbreeding or an independent event of bos primigenius domestication in italy?	when domestic taurine cattle diffused from the fertile crescent, local wild aurochsen (bos primigenius) were still numerous. moreover, aurochsen and introduced cattle often coexisted for millennia, thus providing potential conditions not only for spontaneous interbreeding, but also for pastoralists to create secondary domestication centers involving local aurochs populations. recent mitochondrial genomes analyses revealed that not all modern taurine mtdnas belong to the shallow macro-haplogroup ...	2010	21209945
the complete mitochondrial genome of an 11,450-year-old aurochsen (bos primigenius) from central italy.	bos primigenius, the aurochs, is the wild ancestor of modern cattle breeds and was formerly widespread across eurasia and northern africa. after a progressive decline, the species became extinct in 1627. the origin of modern taurine breeds in europe is debated. archaeological and early genetic evidence point to a single near eastern origin and a subsequent spread during the diffusion of herding and farming. more recent genetic data are instead compatible with local domestication events or at lea ...	2011	21281509
association between muc1 gene polymorphism and expected progeny differences in nelore cattle (bos primigenius indicus).	muc1 is a heavily glycosylated mammalian transmembrane protein expressed by mucosal secretory tissues for both protection against microbial infection and lubrication. an important characteristic of muc1 is its variable number of tandem repeats (vntr) containing several sites for o-glycosylation. vntr length has been associated with many human diseases and with certain economically important traits in domestic ruminants. the aim of the present study was to correlate the length of muc1 gene vntr w ...	2010	21637607
ancient dna extracted from danish aurochs (bos primigenius): genetic diversity and preservation.	we extracted dna from 39 danish aurochs specimens and successfully amplified and sequenced a 252 base pair long fragment of the multivariable region i of the mitochondrial control region from 11 specimens. the sequences from these specimens dated back to 9830-2865 14cyr bp and represent the first study of genetic variation of danish aurochs. in addition, for all specimens we address correlations between the ability to obtain dna sequences and various parameters such as the age of the sample, the ...	2011	22188739
molecular evidence of host influences on the evolution and spread of human tapeworms.	the taeniasis/cysticercosis complex is included in the list of neglected zoonotic diseases by the world health organization due to its significant impact on public health in tropical areas. cysticercosis is still endemic in many regions of asia, africa and latin america. long absent in europe and in other developed countries, cysticercosis has recently re-emerged in the united states and canada, due to immigration, travel and local transmission. this has encouraged the use of molecular data to u ...	2012	22321512
estimation of taurindicine hybridization of american zebu cattle in brazil.	our objective was to estimate bos primigenius taurus introgression in american zebu cattle. one hundred and four american zebu (nellore) cattle were submitted to mtdna, microsatellite and satellite analysis. twenty-three alleles were detected in microsatellite analysis, averaging 4.6 ± 1.82/locus. variance component comparisons of microsatellite allele sizes allowed the construction of two clusters separating taurus and indicus. no significant variation was observed when indicus and taurus mtdna ...	2012	22370942
modern taurine cattle descended from small number of near-eastern founders.	archaeozoological and genetic data indicate that taurine cattle were first domesticated from local wild ox (aurochs) in the near east some 10,500 years ago. however, while modern mitochondrial dna (mtdna) variation indicates early holocene founding event(s), a lack of ancient dna data from the region of origin, variation in mutation rate estimates, and limited application of appropriate inference methodologies have resulted in uncertainty on the number of animals first domesticated. a large numb ...	2012	22422765
spottier targets are less attractive to tabanid flies: on the tabanid-repellency of spotty fur patterns.	during blood-sucking, female members of the family tabanidae transmit pathogens of serious diseases and annoy their host animals so strongly that they cannot graze, thus the health of the hosts is drastically reduced. consequently, a tabanid-resistant coat with appropriate brightness, colour and pattern is advantageous for the host. spotty coats are widespread among mammals, especially in cattle (bos primigenius). in field experiments we studied the influence of the size and number of spots on t ...	2012	22876282
association of single nucleotide polymorphisms in the bovine leptin and leptin receptor genes with growth and ultrasound carcass traits in nellore cattle.	given the important role of leptin in metabolism, we looked for a possible association of leptin and leptin receptor polymorphisms with carcass and growth traits in nellore cattle. we examined associations of leptin and leptin receptor snps with ultrasound carcass (longissimus dorsi muscle area (ribeye area), backfat thickness and rump fat thickness and growth traits (weaning weight adjusted to 210 days of age, yearling weight adjusted to 550 days of age, weight gain of weaning to yearling and s ...	2012	22930433
associations of fasn gene polymorphisms with economical traits in nellore cattle (bos primigenius indicus).	the aim of this study was to identify molecular markers to be applied to marker-assisted selection. three snps of the fasn gene were studied. pcr-rflp was used for genotyping. the snps g.17924a>g, g.17860c>t and g.15603a>g all in the fasn gene were genotyped using the enzymes msci, ddei and hae iii, respectively. the animals were raised in extensive systems and belong to three lines selected for growth as part of the selection program of zebu and caracu breeds, são paulo, brazil. allele and geno ...	2012	22941250
mycobacterium bovis infections in slaughter pigs in mubende district, uganda: a public health concern.	bovine tuberculosis (tb) caused by mycobacterium bovis is primarily a disease of ruminants, particularly cattle (bos primigenius) and buffalo (syncerus caffer), and is endemic in most developing countries. to date, studies done in uganda have documented the prevalence of m. bovis in cattle, humans and wild life, in addition to non-tuberculous mycobacteria in pigs. pigs are increasingly becoming an important component of the livestock sector and share the human ecosystem in rural uganda. it is th ...	2012	22999303
efficacy of diffusion tensor anisotropy indices and tractography in assessing the extent of severity of spinal cord injury: an in vitro analytical study in calf spinal cords.	signal intensity changes observed in magnetic resonance imaging (mri) do not reveal the actual severity of axonal damage incurred in spinal cord injuries. diffusion tensor imaging (dti) is an imaging technique with a potential to track individual nerve fiber tracts.	2012	23245938
tracing the genetic roots of the indigenous white park cattle.	the white park cattle (wpc) is an indigenous ancient breed from the british isles which has a long-standing history in heroic sagas and documents. the wpc has retained many primitive traits, especially in their grazing behaviour and preferences. altogether, the aura of this breed has led to much speculation surrounding its origin. in this study, we sequenced the mitogenomes from 27 wpc and three intronic fragments of genes from the y chromosome of three bulls. we observed six novel mitogenomic l ...	2013	23350719
new world cattle show ancestry from multiple independent domestication events.	previous archeological and genetic research has shown that modern cattle breeds are descended from multiple independent domestication events of the wild aurochs (bos primigenius) ∼10,000 y ago. two primary areas of domestication in the middle east/europe and the indian subcontinent resulted in taurine and indicine lines of cattle, respectively. american descendants of cattle brought by european explorers to the new world beginning in 1493 generally have been considered to belong to the taurine l ...	2013	23530234
genome-wide association study for birth weight in nellore cattle points to previously described orthologous genes affecting human and bovine height.	birth weight (bw) is an economically important trait in beef cattle, and is associated with growth- and stature-related traits and calving difficulty. one region of the cattle genome, located on bos primigenius taurus chromosome 14 (bta14), has been previously shown to be associated with stature by multiple independent studies, and contains orthologous genes affecting human height. a genome-wide association study (gwas) for bw in brazilian nellore cattle (bos primigenius indicus) was performed u ...	2013	23758625
complete mitochondrial genome of wild aurochs (bos primigenius) reconstructed from ancient dna.	extinct aurochs (bos primigenius), accepted as the ancestor of domestic cattle, was one of the largest wild animals inhabiting europe, asia and north africa. the gradual process of aurochs extinction finished in poland in 1627, were the last recorded aurochs, a female, died. some aspects of cattle domestication history and the distribution of aurochs genetic material among modern cattle breeds still remain unclear. analyses of ancient dna (adna) from bone sample deliver new genetic information a ...	2013	23971194
