A comprehensive evaluation of US sheep breeds has not been previously performed; therefore, we evaluated the genetic diversity among and within 28 US sheep breeds. Both major and minor breeds were included in the analysis and consisted of 666 animals from 222 producers loc...

Genetic parameters for a subjective milk score given to ewes within 24 h of parturition were estimated to determine the usefulness of milk score as a selection trait to improve milk production, which influences total litter weight weaned. Heritability of milk score and the genetic correlation of milk score with litter weight weaned were estimated by REML separately for four sheep breeds, Rambou...

Tuj sheep, a well adopted breed for the geography and climate of the highlands, originated in the Caucasus and are found throughout the northeast of Turkey. Although the mature sheep are able to reproduce normally at these conditions, ewe-lambs are normally not able to reach puberty during the first year of their life. Shortage in feed due to long and cold winters together with the seasonality ...

Aim of the study: Karakul sheep farming is one effective subsectors animal breeding in southwestern region Kazakhstan. Sheep coloring a result genetic factors. Breeding can provide farmers with offspring desired color through selection parental couples. Materials: This research introduces an index method for sur-type proportion underfur fibers under 25%. Such provides 15.25% deeper within breed...

Methods – analysis breeding methods, use modern technologies, as well statistical data domestic foreign markets products their processing. Results project "Technology industrial production mutt...

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...
