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...

This study was conducted on four sheep breeds, Karakul, Kajli, Thalli and Kachhi for their natural resistance against Haemonchus contortus. After deworming, 13 animals of each breed were ingested with doses of 5000 L3 of Haemonchus contortus and then evaluation of each was made on the basis of fecal egg count (FEC), body weight, FAMACHA score and packed cell volume (PCV) at different days of in...

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 melanocortin-1 receptor mc1r is encoded by the extension locus, playing a fundamental role in the determination of coat color in a number of mammalian species. however, so far there has been no report regarding the single nucleotide polymorphisms (snps) of the mc1r promoter region and the potential association of its snps with coat color in sheep (ovis aries). throughout the present study, ...

Paratuberculosis as well as the slow virus infections maedi/visna and jaagsiekte came to Iceland in 1933 when 20 sheep of the Karakul breed were imported from Halle, Germany. At least five of these sheep were subclinical carriers of paratuberculosis. Within 16 years paratuberculosis together with the other Karakul diseases (maedi/visna and jaagsiekte) almost ruined sheep farming, the main agric...

Understanding existing levels of genetic diversity of sheep breeds facilitates in situ and ex situ conservation activities. 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...

More than 20.1 million hectares of the territory Republic Uzbekistan are pastures, which 16-17 located in desert region. Karakol sheep, unlike other farm animals, have very valuable biological properties, they able to breed harsh continental climates, sparsely vegetated, saline, arid without consuming absolutely green fodder summer, autumn and winter has ability provide products (astrakhan leat...

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...
