[environmental hygienic aspects of echinococcosis].a literature review on the current situation of echinococcosis in central europe is given. the only final host for echinococcus granulosus in this region ist the dog. the infection rate of dogs with e. granulosus in central europe is less than 1%. according to meat inspection statistics in germany less than 0.008% of sheep, pigs and horses carry larval stages of e. granulosus. parasitologically confirmed is the occurrence of a cattle-dog strain, the cysts of which were found in 0.26% of slaughte ...19921516550
[inquiry of veterinarians in niedersachsen concerning the occurrence of parasitic diseases and their control in large animals].in lower saxony approximately 3500 veterinarians were asked to fill in a questionnaire focused on the prevalence of parasitic infections in cattle, sheep, pigs, and horses, the preferred control measures and the antiparasitic drugs in use. although the disappointing low number of only 48 veterinarians that participated in this survey prevented any representative conclusions the following trends were remarkable: gastrointestinal strongyles were the most prevalent parasites in cattle (34.8%), shee ...19957600943
[observations of the liver copper content in sheep in northwest germany].samples of liver tissue from sheep (n = 231), which were send to the institute on animal nutrition, school of veterinary sciences hannover, were analyzed for copper; the results were evaluated in reference to animal's age and race. in tissue of young sheep (up to 4 weeks) the copper concentration was about 250 (56-770) mg/kg dry matter (dm); values < 120 as well as > 300 mg/kg dm were observed in few cases only. from 198 data of adult sheep 28% suggested a copper deficiency (< 50 mg/kg dm), whil ...19948131730
[development of nutrition science in veterinary medicine as an example of the school of veterinary medicine hannover].animal nutrition is not a main subject in veterinary medicine training, nevertheless it has been taught in the tierärztliche hochschule hannover since its foundation in 1778. in the very beginning only a few lectures about feedstuffs and toxic plants for horses and feeding technique have been presented. during the 19th century animal nutrition was taught about 20 h under the general topic: gesundheitspflege or dlätetik. diätetik included in that time all factors which are important for health as ...19979303852
genetic clustering of borna disease virus natural animal isolates, laboratory and vaccine strains strongly reflects their regional geographical origin.the aim of this study was to gain more detailed insights into the genetic evolution and variability of borna disease virus (bdv). phylogenetic analyses were performed on field viruses originating from naturally infected animals, the bdv vaccine strain 'dessau', four widely used laboratory strains and the novel bdv subtype no/98. four regions of the bdv genome were analysed: the complete p40, p10 and p24 genes and the 5'-untranslated region of the x/p transcript. bdv isolates from the same geogra ...200515659758
prevalence of anti-yersinia outer protein antibodies in goats in lower saxony.little is known about the prevalence of caprine yersiniosis in germany. only few cases are reported every year. the intention of the survey was to provide representative data on the seroprevalence of anti-yersinia antibodies in goats in the german state of lower saxony. a commercially available western blot kit was used to identify caprine and ovine anti-yersinia antibodies against five proteins [yopm, h, d, e and v-antigen (v-ag)]. of the 681 investigated goat sera, 449 (66%) had anti-yop/v-ag ...200515702996
[effects of different selection strategies on breeding towards scrapie resistance in the german grey-horned heath population].scrapie resistance is related to polymorphisms of the prion protein (prp) gene. the homozygous arr/arr genotype of the prion protein gene is associated with high resistance against conventional scrapie infections. but this can lead to a distinct loss of genetic variation in breeds with a small population size or a low frequency of the arr allele. for these populations an optimal breeding scheme for breeding towards scrapie resistance and an arbitrarily chosen production trait with conservation o ...200616555482
high levels of polychlorinated dibenzo-dioxins/furans and dioxin like-pcbs found in monitoring investigations of sheep liver samples from lower saxony, this study, the occurrence of 17 toxicologically-relevant polychlorinated dibenzo-dioxins and furans (pcdd/pcdfs) and 12 dioxin-like polychlorinated biphenyls (dl-pcbs) was investigated in livers of sheep from lower saxony, germany. the aim of the monitoring was to get a state-wide picture on the contamination level of sheep liver samples. seventy two out of 77 investigated sheep liver samples exceeded the european maximum tolerance level for pcdd/pcdfs of 6.0 pg who-pcdd/f-teq g(-1) fat with ...201020045173
emergence of bluetongue virus serotype 6 in europe--german field data and experimental infection of late 2008, bluetongue virus (btv) serotype 6 (btv-6), which had never occurred in europe before, was first detected in the netherlands and germany. while the origin of the virus remains unknown, the prevalence of infections in cattle was investigated in a virological (n=28,658) and serological (n=2075) field survey in lower saxony, where 45 cases confined to the district grafschaft bentheim were found. blood from affected animals was used for the experimental infection of three cattle with di ...201020045271
risk factors for bse-infections in lower saxony, order to generate data on the cattle population and farm management in the state of lower saxony, germany, a basic demographic survey was conducted. afterwards these bse-free farms as a reference population were compared with the population on bse farms to identify risk factors for bse infections. a variety of risk factors for bse were reviewed, including the import of cattle from the united kingdom, commercial foodstuff, dairy farming, herd size and cross-contamination with foodstuff for oth ...200817764771
[influence of prion protein gene polymorphisms on performance traits in german meat sheep breeds].prp polymorphisms influence the scrapie susceptiblility of sheep. the objective of this study was to analyse the association between performance traits and the prp genotype in the sheep breeds german black-headed and german white-headed mutton, bleu du maine, german mutton merino, leine, texel and suffolk from lower saxony and westphalia. we analysed performance traits such as scores for muscle mass, type and wool quality and the calculated daily weight gain using linear animal models. in all se ...200415503534
[animal welfare service of lower saxony--first report of experiences].the animal welfare service of lower saxony-part of the state veterinary services within the regional government of weser-ems-started its work in february 1995 at oldenburg. the experiences during the first 18 months of activity are discussed. the main duties of the service consist of: advising the local district veterinary authorities concerning "problem" holdings including common control visits on occasion. advising the offices of the court on matters concerning animal protection. advising gove ...19979157004
[genotype effects of milk protein polymorphisms on milk production in east friesian dairy sheep].the frequencies of milk protein variants alphas1-casein, alphas2-casein, beta-casein and beta-lactoglobulin were determined in 182 milk sheep from 7 flocks in lower saxony and saxony. the genotype effects of these polymorphic milk protein variants on milk performance traits were estimated for 173 ewes using a test day model with fixed regression.the model included the fixed effects of colour variant of the breed, region, lambing season, lambing year, lactation number and number of lambs born. th ...200415495933
biospheric 129i concentrations in the pre-nuclear and nuclear order to detect characteristic regional differences or temporal changes of 129i concentrations in the biosphere, thyroids from humans, grazing livestock, and herbivorous wildlife species (reindeer and roedeer) were collected in various areas of the world which are not affected by reprocessing plants. for reasons of comparison, all samples were analyzed for their 129i:127i atom ratios. human and bovine thyroids taken from the 10th region in southern chile (39 degrees-41 degrees south) indicate ...19938244695
