Scrapie is a fatal neurodegenerative disease of sheep and goats belonging to the group of transmissible spongiform encephalopathies (TSE). TSEs are characterised by distinctive pathology, the involvement of a hostencoded prion protein (PrP) in disease development and genetic control of susceptibility. Polymorphisms in three different codons of the ovine prion protein (PrP) gene (136, 154, 171) ...

Nepal borders India in the south and China in the north. Four distinct indigenous domestic sheep breed, i.e. Bhyanglung in the alpine region, Baruwal in the high hills, Kage in the mid hills and Lampuchhre in the low lands are distributed in the country. In this study, the mitochondrial DNA control region of 111 sheep from these four breeds was directly sequenced to determine their genetic vari...

in this study a set of 10 polymorphic microsatellites (maf33, oarcp34, bm8125, maf214, maf70, dyms1, mcm527, oarjmp29, oarjmp58, bm1824) has been used to assess the distribution of genetic variation in six iranian sheep breeds (sanjabi, kabude shiraz, turki ghashghaii, lori, bakhtiyari and arabi). from each breed 45 sheep randomly were selected and their blood samples were collected individuall...

We identified 37 single-nucleotide polymorphisms (SNPs) in sheep and screened 16 individuals from 8 different sheep breeds selected throughout Europe. Population genetic measures based on the genotyping of about 30 sheep from the same 8 breeds are reported. To date, there are no sheep SNPs documented in the National Center for Biotechnology Information dbSNP database. Therefore, the markers pre...

Sheep breeds show a broad spectrum of different horn phenotypes. In most modern production breeds, sheep are polled (absence of horns), whereas horns occur mainly in indigenous breeds. Previous studies mapped the responsible locus to the region of the RXFP2 gene on ovine chromosome 10. A 4-kb region of the 3'-end of RXFP2 was amplified in horned and polled animals from seven Swiss sheep breeds....

Locally adapted breeds of livestock are of considerable interest since they represent potential reservoirs of adaptive fitness traits that may contribute to the future of sustainable productivity in a changing climate. Recent research, involving three hill sheep breeds geographically concentrated in the northern uplands of the UK has revealed the extent of their genetic diversity from one anoth...

The present investigation was to study DNA polymorphism of insulin-like growth factor binding protein-3 (IGFBP-3) gene by PCR-RFLP in four Egyptian local sheep breeds. Genomic DNA was isolated from a total of 20 animals from four Egyptian breeds (five each) of sheep namely Rahmani, Ossimi, Awassi, and Barki. A fragment of IGFBP-3 gene, comprising of a part of exon 2, complete intron 2, exon 3, ...

Six morphometric traits (height at withers, body length, chest girth, ear length, tail length and body weight) were analyzed to characterize from a breed point of view 1981 sheep from four ovine breeds (Bellary, Kenguri, Hassan and Mandya) of southern peninsular zone of India. Discriminant Function Analysis was used to distinguish between four breeds by morphometric traits. The population varia...
