female choice selects for a viability-based male trait in pheasants.recent theory on sexual selection suggests that females in species without paternal care choose mates by their secondary sexual characters because these indicate genotypic quality which will be transmitted to the offspring. these ideas are not yet empirically supported as data quantifying the relationship between female mate choice and female reproductive success are lacking. only in one case, in colias butterflies, has it been demonstrated unequivocally that females choose 'good genotypes' as m ...19892911350
rapid induction of b-cell lymphomas: insertional activation of c-myb by avian leukosis virus.eu-8 is a recombinant avian leukosis virus (alv) constructed in vitro, which carries long terminal repeats and gag and pol genes from ring-necked pheasant virus and the env gene from ur2av. unlike either parent virus, when injected into 10-day-old chicken embryos, eu-8 induces a high incidence of clonally arising b-cell lymphomas within an unusually short latent period, often causing death within 5 to 7 weeks after infection. these tumors differ from the classic lymphoid leukosis induced by alv ...19882831403
[susceptibility of birds other than chickens to infectious laryngotracheitis].susceptibility to infectious laryngotracheitis virus was studied in peafowl (pavo cristatus), various species of pheasant (phasianus colchicus, lophura swinhoeii, lophophorus impejanus), guinea-fowl (numida meleagris), canaries (serinus canaria), budgerigars (melopsittacus undulatus) and japanese quail (coturnix coturnic japonica). apart from clinical observations, experiments were evaluated in terms of histopathology, immunofluorescence, serology and recovery of virus. only peafowl and pheasant ...19852990066
genetic determinants of neoplastic diseases induced by a subgroup f avian leukosis virus.two subgroup f avian leukosis viruses, ring-necked pheasant virus (rpv) and rav-61, were previously shown to induce a high incidence of a fatal proliferative disorder in the lungs of infected chickens. these lung lesions, termed angiosarcomas, appear rapidly (4 to 5 weeks after infection), show no evidence of proto-oncogene activation by proviral integration, and are not induced by avian leukosis viruses belonging to other subgroups. to identify the viral sequences responsible for induction of t ...19873029416
vertebrate host specificity and experimental vectors of plasmodium (novyella) kempi sp. n. from the eastern wild turkey in iowa.vertebrate host specificity, experimental laboratory vectors, and a description of plasmodium (novyella) kempi sp. n. from eastern wild turkeys (meleagris gallopavo silvestris vieillot) in iowa are presented. plasmodium kempi is infective for domestic turkeys, bobwhites (colinus virginianus), chukars (alectoris graeca), guinea fowl (numida meleagris), peacocks (pavo cristatus), and canaries (serinus canaria), produces a transient infection in mallards (anas platyrhynchos) and domestic geese (ans ...19836644918
proliferative fibromatosis in avian skeletal muscle caused by cloned recombinant avian leukosis viruses.two molecular recombinants (eu-8 and k-3) constructed from ring-necked pheasant virus and ur2av, the helper virus associated with avian sarcoma virus ur2, caused a high incidence of a hitherto unreported pathological condition in chick skeletal muscle. a disease spectrum was observed in which muscle was infiltrated by proliferating fibroblasts and caused white streaks, white diffuse areas, or well-defined elongated tumors. fibroblast proliferation was progressive, and the gross presentation depe ...19873030543
annual cycles of plasma gonadotropins and sex steroids in japanese common pheasants, phasianus colchicus versicolor.plasma levels of fsh, lh, and sex steroid hormones were monitored individually in 5 male and 15 female japanese common pheasants once to thrice monthly for 13 months. the birds were reared in outdoor cages, each containing 1 male and 5 females, under natural conditions of temperature and photoperiod. around the period of egg laying from april 19 to july 6, plasma levels of fsh, lh, estradiol-17 beta (e2), and progesterone (p) in females were high. the increases in circulating fsh and e2 occurred ...19863096815
structure and concentrating ability in the avian kidney.we quantified various aspects of the morphology of the kidney in seven bird species and related these measures to urinary concentrating ability (the concentration of ureteral urine in dehydrated animals) for six of the species. kidney mass, number of glomeruli, and number of medullary cones all tended to increase with body mass. smaller birds, with smaller kidneys, had smaller nephrons with smaller glomeruli. lengths of medullary cones tended to increase with body mass and were exceptionally lon ...19892916702

nucleotide sequences derived from pheasant dna in the genome of recombinant avian leukosis viruses with subgroup f specificity.recombination between viral and cellular genes can give rise to new strains of retroviruses. for example, rous-associated virus 61 (rav-61) is a recombinant between the bryan high-titer strain of rous sarcoma virus (rsv) and normal pheasant dna. nucleic acid hybridization techniques were used to study the genome of rav-61 and another rav with subgroup f specificity (rav-f) obtained by passage of rsv-rav-0 in cells from a ring-necked pheasant embryo. the nucleotide sequences acquired by these two ...1977199737
[ecology of syngamosis in a large scale farming area].within recent 20 years, czechoslovak agriculture has undergone considerable changes due to the introduction of largescale farming. our contribution presents the results of studies on chickens (gallus gallus f. dom.) reared traditionally on runs in an area contaminated with the eggs of syngamus trachea distributed with pheasant faeces. in addition to postmortem examination of 336 chicken tracheae, their faeces collected for one year from the runs were examined, but syngamosis was not found. studi ...1976137683
evolutionary shift in the site of cleavage of prelysozyme.sequences are presented for the signal peptides of prelysozymes from 6 species of birds and compared to the known sequence for chicken prelysozyme c. the sequencing was done with synthetic oligonucleotides as primers and oviduct mrna as the template, obviating the need to clone dna from these species. ring-necked pheasant prelysozyme c differs from all other prelysozymes c and pre-alpha-lactalbumins examined by being cleaved in vivo between amino acid residues 17 and 18 instead of between residu ...19863511061
light and electron microscopy observations in the thyroid gland of the pheasant (phasianus colchicus l.).in the summer, the pheasant thyroid presents as a relatively quiescent organ with reduced secretory activity; the follicular epithelium is very low and mostly of the pavement type, while the follicles are unwontedly large and contain an increased amount of colloid. the follicular cell cytoplasm contains numerous characteristic spherical vacuolar structures. in the winter, however, the thyroid displays remarkable reconstruction and raised activity of the follicular cells, which are much higher an ...1977616682
treatment of nematodiasis in poultry and game birds with fenbendazole.administration of 100 ppm fenbendazole to 661 pheasants (phasianus colchicus colchicus) and 25 partridges (perdix perdix) for 4 days reduced natural infection with syngamus trachea and/or capillaria obsignata and in some cases with heterakis spp. by more than 90%. a 5-day administration of feed medicated with 30 or 60 ppm fenbendazole resulted in almost 100% efficacy against natural c. obsignata and heterakis gallinae infection in 343 pullets. the treated pullets were kept under poor hygienic co ...19846743169
ahemeral light-dark cycles and egg production parameters of ring-necked pheasants (phasianus colchicus).the effects of two ahemeral light-dark (l:d) cycles on ring-necked pheasant egg production were investigated in this experiment. three groups of 36 female and 12 male 10-month-old birds were exposed to control 24-hr (14l:10d), ahemeral 22-hr (14l:8d), or ahemeral 26-hr (14l:12d) l:d cycle. average percent hen-day egg production (hdep) was 63.8 for hens exposed to ahemeral 26-hr l:d cycle compared with 55.6% hdep for the controls. although this was not significant (p less than .05). it suggests a ...19873588492

pharmacokinetics of a long-acting oxytetracycline preparation in ring-necked pheasants, great horned owls, and amazon parrots.after a single iv or im dose of a long-acting oxytetracycline (otc) preparation, serum concentrations were determined at various times in the ring-necked pheasant, great horned owl, and amazon parrot. pharmacokinetic parameters, including serum half-life (t1/2) and apparent volume of distribution (vd) were calculated from the otc concentration-time curves for each species and route of administration. significant differences (p less than 0.05) were found in the t1/2 and vd parameters between spec ...19854083606
transmission of histomonas meleagridis to domestic fowl by means of earthworms recovered from pheasant yard soil.four cockerels and two poults were fed ground earthworms recovered from soil where ring-necked pheasants (phasianus colchicus) were raised. all 4 cockerels showed mild signs of histomoniasis, and numerous heterakis were recovered at necropsy. one of the 2 poults died, with typical gross and microscopic lesions of histomoniasis. heterakis eggs recovered from the 4 cockerels were used to infect an additional 12 cockerels and 11 poults.19751239268
isolation of the pigeon pmv-1 variant of newcastle disease virus from imported pheasants (phasianus colchicus).isolation of a virulent pigeon paramyxovirus 1 (ppmv-1) strain of newcastle disease virus (ndv) from pheasants imported for release is reported. although no clinical signs or postmortem lesions suggesting ndv infection were detected, the intestine was processed for attempted virus isolation as part of a surveillance programme on wild-bird populations. the potential role of pheasants as carriers of the disease, and the importance of developing surveillance programmes for wild bird populations is ...19947597861
effect of t-lymphocyte depletion on the pathogenesis of marble spleen disease virus infection in ring-necked pheasants.the purpose of this study was to determine the effect of cyclosporine (csp)-mediated t-lymphocyte depletion on the pathogenesis of marble spleen disease virus (msdv) infection in ring-necked pheasants. seventy-two 6-week-old pheasants were divided into three groups; one group of 18 birds was inoculated with msdv, a second group of 18 birds was treated with csp, and a third group of 36 birds was both treated with csp and inoculated with msdv. two birds each from both of the smaller groups and fou ...19957794193

changes in ring-necked pheasants' (phasianus colchicus) egg formation time, oviposition lag time, and egg sequence length due to ahemeral light-dark cycles.a total of 108 pheasant hens was exposed to either a conventional 24-hr (14l:10d), an ahemeral 22-hr (14l:8d), or an ahemeral 26-hr (14l:12d) light-dark (l:d) cycle. total lag time for each egg sequence was greater in the ahemeral cycles than in the conventional l:d cycle, resulting in significant (p less than .05) differences in egg formation times (eft) or intraclutch intervals of 26.4, 25.8, and 27.5 hr, respectively. the eft under the ahemeral 26-hr l:d cycle was synchronized (within 1.5 hr) ...19873588490
weight, carcase composition and reproductive performance of pheasants (phasianus colchicus) fed restricted or unrestricted diets.artificially reared hen pheasants, released in summer, are reported to have little reproductive success in the wild the following spring. one possible explanation is that such birds are unable to obtain an adequate diet after supplementary feeding ceases in february. when captive hen pheasants were fed an unrestricted diet they maintained constant muscle mass and fat reserves throughout the laying period. hens restricted to pre-lay maintenance levels of nutrition after photostimulation initially ...19947973085
