WOOL PRODUCTIVITY AND QUALITY OF RUSSIAN MEAT MERINO SHEEP FROM INTRA- AND INTERLINE SELECTION

Line breeding is often used in purebred animal husbandry, although the combination of lines may affect undesirable result. Therefore, it very important for breeders to know which animals can be combined produce highly productive offspring with high meat and wool properties. This article studies influence interline selection Russian merino breed on productivity, quality skin histostructure. We found that highest clipping was group III obtained from ME-50 line rams AS-30 ewes. Ewes exceeded their peers II intraline AC-30 IV queens. At same time, ewes insignificantly I by 2.0% (P>0.05). Animals had rather fleece indices terms condition due rams. Moreover, they ratio “fat:sweat” (0.84), confirms technological properties this genotype. The sheepskins depends nature connection collagen fibers reticular layer. In thickness layer young groups I, 5.3% (P> 0.05), 21.9% ( P<0.01) 12.0% (P<0.05) respectively.
