Abstract Background Sheep milk is a nutritional and health-promoting food source for humans. The DEATH superfamily conserved protein family, some of its members are closely related to lactation. Systematic studies the important further understanding functions in mammary gland during lactation; however, there currently lacking. Results Herein, 74 were identified sheep, phylogenetic analyses indi...

Abstract Introduction Diet selection of grazing livestock is one the critical factors affecting diversity and composition plant communities in grasslands, with consequent impacts for ecosystem functioning. Co‐grazing multiple species could create additive or complementary effects on due to diet overlap differentiation among species. However, there only limited knowledge about co‐occurring wheth...

One-hundred and three Unites States Suffolk sheep were inoculated orally with a scrapie agent preparation and monitored for clinical disease and histopathological lesions characteristic of scrapie. A retrospective study of the polymorphisms at codon 171 of the prion protein (PrP) gene was performed on these sheep. All 63 sheep that developed scrapie during the observation period were homozygous...

BACKGROUND The prevalence of Salmonella in food producing animals is very low in Sweden due to rigorous control programmes. However, no active surveillance is in place in sheep. The authorities decided to perform a prevalence study in sheep herds because findings at slaughter indicated that sheep associated S. diarizonae (S. enterica subspecies diarizonae serovar 61:(k):1, 5, (7)) might be comm...

Background: Camel and sheep have high disperse and tolerance in tropical regions. But different results of harsh condition tolerance ability of them have been reported. ObjectiveS: The objective of this study was to determine the heat stress tolerance in camel and sheep by evaluating changes in blood serum metabolites and to report and compare the serum biochemical profile of sheep and camel du...

Border disease is a congenital viral disease of sheep and goats and cause significant economic losses worldwide. It may cause abortion in sheep. However, there isn’t any report of ovine abortion due to this virus from Iran. The aim of the present study was to investigate the role of this viral infection in sheep abortions in Chaharmahal and Bakhtiari province. To this end, 100 samples of aborte...

In autumn 2006, a study of the age-dynamics of Echinococcus granulosus cyst abundance was undertaken from an abattoir study of 1081 sheep slaughtered in Naryn Province in central Kyrgyzstan, an area endemic for echinococcosis. The results demonstrated approximately 64% of sheep were infected with the prevalence increasing markedly with age. The mean abundance was 3.8 cysts per sheep. From estab...

Serum samples from 600 sheep were collected from 5 different provinces randomly chosen in South Africa. Two sheep abattoirs (representing formal slaughter of sheep) and 1 rural location (representing informal slaughter of sheep) per province were also selected randomly. The serum samples were tested for anti-Toxoplasma gondii IgG antibodies using 2 different serological tests: an indirect fluor...

In many Norwegian alpine and tundra areas sheep and reindeer graze sympatrically. Areas covered with dung or urine may have consequences for reindeer pasture utilization. Experiments were conducted on 5 stall fed male reindeer calves where animals were individually presenred with two troughs (experimental and control) containing 200 g of concentrate. Fresh and dry sheep and reindeer pellets (50...

BACKGROUND A study to investigate transmission of classical scrapie via goat milk was carried out in sheep: firstly, lambs were challenged orally with goat scrapie brain homogenate to confirm transmission of scrapie from goats to sheep. In the second study phase, milk from scrapie-infected goats was fed to lambs. Lambs were selected according to their prion protein gene (PRNP) genotype, which w...
