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...

Previous studies on mitochondrial DNA analysis of sheep from different regions of the world have revealed the presence of two major- A and B, and three minor- C, D and E maternal lineages. Lineage A is more frequent in Asia and lineage B is more abundant in regions other than Asia. We have analyzed mitochondrial DNA sequences of 330 sheep from 12 different breeds of India. Neighbor-joining anal...

The objective of this study was to determine the relationship between body weight (BW) and heart girth (HG) in Sardi and Timahdite sheep in order to develop a prediction equation of BW from HG. The data used for this study included 476 records on BW and HG (227 in Sardi and 249 in Timahdite) collected on males and females of different ages in 33 private farms. The BW and the HG averaged 34.8 ± ...

b-lactoglobulin (coded by the b-lg gene) is the major milk whey protein in ruminants. studies have shown that this protein is polymorphic in many breeds of sheep as a result of a single base pair substitution in the b-lg gene that also gives rise to rsai restriction fragment length polymorphism (rflp). blood samples were collected from 391 animals belonging to 5 iranian and 6 russian sheep bree...

The main focus of this research is to determine the molecular phylogeny and characterization Mundri Sheep (Ovis aries) through sequencing mitochondrial Cytochrome b Oxidase Subunit I (COI). This sheep breed appears morphologically different from other local breeds Pakistan. current carried out appraise status whether it aa or not. Blood samples were collected Livestock Experiment Station, (LES)...

Batur sheep is one of Indonesian’s local species with the original geographical distribution in District and surrounding areas. This study was conducted to determine suitability that were kept by smallholder farmers. The Village, Banjarnegara Regency, Indonesia February 2020 identifying qualitative traits sheeps (64 males 129 females) compared other breeds. Qualitative data then transformed int...

The Qira black sheep and the Hetian sheep are two local breeds in the Northwest of China, which are characterized by high-fecundity and low-fecundity breed respectively. The elucidation of mRNA expression profiles in the ovaries among different sheep breeds representing fecundity extremes will helpful for identification and utilization of major prolificacy genes in sheep. In the present study, ...
