Stages of formation and prospects of development of salskaya sheep breed
Salskaya breed of sheep relates to a small domestic breeds, which by its productive qualities and adaptation is of significant interest in the development of national genetic resources in sheep breeding. The article gives characteristics of the main stages of formation and modern status of the breed. In the selection process it is important to use not only traditionally actively promoted in the market tribal resources rocks and herds, but also small domestic breeds, the potential of which is used very poorly. Such species include Sal, tested and recognized a selection achievement in 1950. By the end of 70-ies of the herd stud them. S. M. Budyonny remained the most numerous and the most productive among the other breeding herds salskaya breed. Ewes and bright had a large stock of leather in the form of well-developed Burda and apron at the neck, "socket" at the root of the tail and visible Marinetti on the body, noticeable in the cut animals. Length of wool of the annual growth rate was 7 - 8 cm. The content of suint in the fleece composition reached 50-55 %, and the yield of pure wool does not exceed 34 to 38 %. The second stage can be considered as a period when for the improvement of salskaya breed were not only inbreeding breeding that has always been a priority in breeding work with a herd of wooly productivity, but also brought resources breeds Soviet Merinos and Stavropol. The third stage of the breed was the period when the country to improve the Merino sheep have begun to use the Australian Merino. The sheep got a new very valuable properties, which have become an important element of the collective genotypes: significant improvement in oprelosti of the body, primarily the back and belly, tight closed fleece, clear tortuosity of wool combined with elasticity, wool grease of optimum quality and quantity, a significant increase in the yield of clean wool, in most cases, increasing the wool yield of pure wool, an optimized supply of the skin, increased length of wool in sheep at 10-11 % compared with the old type of the breed. At this stage, to expedite the process, was attracted by the potential of the Stavropol breed breeding farm "Second five-year plan", improved Australian meat Merino. The article characterizes the direction of work on creation of new inbreeding type.
