Sheep display a variant phenotype with respect to their susceptibility to copper and derivative pathology. The North Ronaldsay sheep are acutely sensitive to environmental copper while the Cambridge breed is much more copper-tolerant. A study of protein expression in the liver of the two different breeds of sheep as a result of copper challenge would aid in the understanding of their differing ...

The present study was carried out at Governmental Research Centre for Conservation of Sahiwal Cattle (RCCSC) Jahangirabad, District Khanewal during 2007, to investigate the overall prevalence of Ostertagia spp., in sheep. Out of 300 hosts 231 were infected with Ostertagia spp. The overall prevalence of Ostertagia spp. was (77%). The males showed significantly (P<0.05) higher prevalence (81.4%) ...

BACKGROUND Commercial sheep raised for mutton grow faster than traditional Chinese sheep breeds. Here, we aimed to evaluate genetic selection among three different types of sheep breed: two well-known commercial mutton breeds and one indigenous Chinese breed. RESULTS We first combined locus-specific branch lengths and di statistical methods to detect candidate regions targeted by selection in...

Threat Assessment of Red-and-blue lory, particularly a case study on illegal hunting and habitat destruction using direct observation methods in the natural red-and-blue specifically within lory Conservation Area at PT Pertamina Patra Niaga Integrated Terminal Bitung Beo District, Kepulauan Talaud Regency, Indonesia. This research aims to determine factors that influence destruction, which have...

The number of lambs sold per ewe mated in the breeding flock has a considerable impact on sheep operation profitability. This depends primarily on fertility, prolificacy (# of lambs), and lamb survival, mothering ability, milk production of the ewe and lamb growth rate. Optimal reproduction does vary by environment and management system – some sheep operations don’t want a lambing rate over 200...

Lactating St. Croix White and Dorper × St. Croix White ewes were used to evaluate the effect of breed and feeding a split ration on body temperature during the cool (March–April) and warm (July–August) seasons in the U.S. Virgin Islands. Within each season ewes were assigned to treatments (n = 8/treatment) based on breed, age, and number of lambs. Treatments consisted of individually feeding ew...

This paper concerns the likely origin of three mutations with large effects on ovulation rate identified in the Belclare and Cambridge sheep breeds; two in the BMP15 gene (FecX(G) and FecX(B)) and the third (FecG(H)) in GDF9. All three mutations segregate in Belclare sheep while one, FecX(B), has not been found in the Cambridge. Both Belclare and Cambridge breeds are relatively recently develop...

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 main objective of this study was to assess the concentration various minerals (Ca, P, Mg, Cu, Zn, Fe) in blood sheep, followed by biochemical analysis order reveal possible associations season and breed. conducted sampling four herds: Suffolk (n=20), Merino Lithuanian blackhead (n=20) Charolaise (n=7). first collection April last one performed February. highest level Ca estimated ewes, lowe...

Implementation of genomic selection in sheep breeding provides a number of challenges, compared to dairy cattle, because of the higher genetic diversity between and within sheep breeds, the cost of maintaining reference populations and the limited ability of individual breeders to invest in genotyping. Within this study, we compare theoretical and realized genomic prediction accuracies for trai...
