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 genotypes of the melatonin receptor 1A (MTNR1A) were determined by PCR-RFLP in the native Iranian Shall  and karakul breeds of sheep . Blood samples were collected from 60 karakul and 50 Shall breeds. Genomic DNA was extracted based on the Guanidin Thiocyanate-slica gel method. After PCR reaction, PCR products were digested by the Mnl1 restriction enzyme. The MTNR1A locus had two genotypes ...

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 ± ...

Karakul sheep breed has a lot to offer to livestock production in many parts of Botswana. This breed of sheep is acclimatised to desert conditions, which prevail in most parts of Botswana. This breed produces a range of products viz meat, milk, fur/pelt and wool, allowing for diversification of farm produce hence reduced risks attached to the production of a single product. The Karakul breed ha...

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, ...

Tibetan sheep, an indigenous breed, have a wide variety of phenotypes and a colorful coat, which make this breed an interesting model for evaluating the effects of coat-color gene mutations on this phenotypic trait. The agouti signaling protein (ASIP) gene is a positional candidate gene, as was inferred based on previous study. In our research, ASIP gene copy numbers in genomic DNA were detecte...

An objective and accountable method is needed for deducing the number of registered animals in a breed from registration data. By following the principle that individual breeders register sufficient young females to be certain of having enough replacements for their current breeding stock, the ratios were calculated of the number of adult females in a breed to the number of female registrations...
