Serum biochemical traits constitute important panels in the clinical diagnosis, prognosis and treatment of livestock diseases via the investigations of myriads of parameters influencing these biochemical references. Sixty clinically healthy animals of three extant breeds of Nigerian native sheep (20 Balami: 20 Yankassa and 20 Uda) were sampled to examine the roles of breed, age and sexual dimor...

BACKGROUND The objective of this proteomics study was to identify proteins that changed expression as a result of copper challenge in the uniquely copper sensitive North Ronaldsay sheep and further, to compare those changes in expression with the more copper tolerant Cambridge breed. Such data gives us a proteome-centered perspective of the pathogenesis of copper-induced oxidative stress in thi...

The article presents the results of a biochemical and morphological analysis pure blood cross-bred sheep Edilbaevsky breed, born in different seasons year. parameters animals studied groups by us were within physiological norm, but there some differences between groups. It was found that redox processes body cross-breed group more intense than peers same group, which turn affected higher indica...

Relevance. The article provides a justification for the use of sheep selection taking into account intra-breed type Prekos ewes in purebred breeding and crossing with producers semi-fine wool breeds Romney-Marsh Kuibyshevskaya to improve biological usefulness meat offspring. Methods : scientific economic experiment different options, productive Precos breed. Results. presents results study on i...

Eperythrozoonosis is a small ruminant disease caused by the bacterium Mycoplasma ovis (formerly known as Eperythrozoon ovis). Whilst acute infection in sheep may result in an anaemia and ill thrift syndrome, most animals do not develop clinical signs. Molecular methods were used to compare and evaluate the prevalence of infection with M. ovis in sheep and goats in Tunisia. A total of 739 whole ...

The Australian Merino is the most important genetic resource for the wool and the lamb and sheep meat industries of Australia. In this paper estimated genetic parameters for ultrasound scan and wool traits at yearling and hogget age are presented for Merino sheep. Results indicate that it is possible to breed Merino sheep that perform well for both ultrasound scan and wool characteristics when ...

Bluetongue is a primarily midge-borne devastating hemorrhagic viral disease of sheep characterized by high morbidity and mortality resulting severe economic losses to sheep farmers. An epidemiological study was undertaken to assess the crude and specific measures of morbidity, mortality and case fatality against bluetongue in sheep. In this study, a total of 11 bluetongue outbreaks were selecte...

Paiva et al. (2011) examined how microsatellite loci data from sheep surveys in the United States and Brazil could be merged when they are analyzed in different laboratories. In addition, they calculated the inbreeding coefficient using F IS from the software FSTAT (Goudet 2001) using the formula F H H IS O E 1 = − / , where H O and H E are the observed and expected Hardy–Weinberg heterozygosit...
