Productivity of akzhaik meat-wool sheep and their hybrids derived from rams from the North Caucasus and Kuibyshev breeds

Currently in a herd of Akzhaik meat-wool sheep breeding work is carried out to improve productive, tribal and biological qualities. breed properties through the use of genetic the potential of the gene pool of semi-fine sheep under conditions of Padno-Kazakhstan region. Studies were performed in OPH "Atameken" NAO ZKATU named after Zhangir Khan. Were formulated world groups and implemented the following options selection: Group I - rams-producers and queen akameat and wool breed; Group II - sheep- half-blooded North Caucasian meat-wool sweaters with Akzhaik meat-woolly uterus; Group III - Kui Byshevsk sheep manufacturing (in the type of Romney March) with Akzhaik meat-woolly uterus. The article gives The research data of productive indicators of Jaika meat-wool sheep and sheep producers North Caucasian and Kuibyshev breeds used in insemination of uterus, as well as reproductive ability the quality of the queens and the safety of the young. Determined that used in the experiment semi-fine-rooted rams meat and wool breed breeds with crossbred wool Steas were characterized by rather high rates. meat and wool productivity. Physical research co-technical properties of wool showed that they are requirements of a cross-bred homogeneous whoa. The average hair length of all queens was 11.2 cm, that meets the requirements of the first bonding class according to the standard. The results of lambing are Does the fertility of queens in compared groups groin was about the same and ranged within 92.0-96.0% with a slight advantage in the first group, where on both sides were Aczhaik sheep that exceeded the second and third groups by 3.0-4.0%. Waste lambs in all groups ranged from 7.0% - for ak Zhaikis and 2.6-2.7% - in hybrids of 1/2 CK and KB of rams. The best fecundity differed uterus first and second groups - 120.0 and 120.6%. Marked high business the course of the lambs in the selection options where the production The bodies of 1/2 SK and KB of rocks are explained by the effect of heterosis.
