This article presents the results of clinical and laboratory studies on examination sooty Karakul sheep. farming is one main branches animal husbandry, today some 6 million sheep are raised in desert semi-desert pastures Republic. The productivity most rangelands these areas low, this figure largely dependent atmospheric precipitation. In addition, global problem warming causing a sharp drop Pa...

This study was conducted to estimate genetic distances among Akkaraman, Morkaraman, Awassi, Merino, Karakul, Kivircik, Imroz, Daglic and Karayaka sheep breeds reared in Turkey based on simple polymorphic blood protein types by using various methods including horizontal strach gel electrophoresis and polyacrilamyde gel electrophoresis (PAGE). NJ and UPGMA trees were constructed based on genetic ...

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...

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, ...

The study was conducted on 85 neonatals of Pak-Karakul sheep at the Sheep and Goat Development Centre, Rakh Khairewala, District Layyah, Pakistan, with the aim of assessing the relationship of immunoglobulins to neonatal lamb mortality. Overall mortality in neonates was 8.24%. Surviving lambs (3.77±0.07 kg) were significantly (P<0.001) heavier than those that died during the neonatal period (2....

Homozygous grey and white Karakul lambs die after they have reached weaning age. This is due to a lethal gene causing digestive disturbances. Previous studies revealed that grey and white lambs have large, milk-filled rumens; the phenomenon was attributed to a significant decrease in the number of myenteric ganglia and neurons in the rumen wall. This study was undertaken to determine whether an...

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...

Homozygous grey Karakul lambs are born with a lethal genetic factor responsible for death at weaning age. When put on a high roughage diet under field conditions they develop distended, thin-walled rumens and sand impacted abomasa. Homozygous white Karakul lambs have a similar factor but survive for a longer period. Black Karakul lambs are not affected. The present study was undertaken to compa...
