T HE development of the Targhee breed of sheep began in i9=6 when the Bureau of Animal Industry at the U. S. Sheep Experiment Station, Dubois, Idaho mated select Rambouillet rams with select ewes of Corriedale XLincoln-Rambouillet and Lincoln XRambouillet combinations. Descendants of these crosses have been interbred and carefully selected to produce Targhee sheep. Spencer and Stoehr (x94L) hav...

Phylogenetic relationships and genetic variation between two Iranian sheep breeds were analyzed using cytochrome b (cyt-b) gene sequences. The genomic DNA was isolated by salting out method and amplified cytochrome b gene using polymerase chain reaction restriction (PCR) method with a pair of primer. A partial sequence of cyt-b gene of Iranian sheep is 780 bp and contained 13 variable sites and...

the major histocompatibility complex (mhc) plays a central role in the control of disease resistance and immune response. extensive genetic diversity in mhc genes provides a valuable source for genetic improvement, via selection, in many domestic animals. exon 2 of the class ii mhc, termed ovar-drb1 in domestic sheep (ovis aries), has been suggested as important disease resistance and immune re...

kermani sheep breed is one of the major sheep breeds in iran, especially in kerman province for which no study has yet been carried out through y-chromosome specific microsatellite markers. throughout this study, amplification quality related to 17 bovine y-chromosome specific microsatellites was evaluated for the mentioned sheep breed. one hundred males and twenty females of non-related animal...

In Pakistan, parasitic infections are among major constraints to animal production. Gastro-intestinal (GI) parasites cause huge economic losses (direct or indirect) to livestock. In Pakistan, distribution and effect of GI parasitism in sheep is not very well studied. The present study was conducted to determine the prevalence of GI parasites in sheep population of Sialkot district, Punjab, Paki...
