Abstract

In order to assess the productive and biological characteristics of growing sheep of different origin we have carried out commercial cross breeding of Kyrgyz hair fat-tailed sheep with dairy Awassi sheep imported from Israel. As a result of basic measurements of body type it was established that crossbred descendants differed with better proportion of majority of body statures with well demonstrated meat and milk shapes. The duration of lactation period with crossbred females of first generation is longer for 50 days, but milk yielding capacity - 88,7 l more than of females of Kyrgyz hair sheep population. Generally having analyzed the effectiveness of crossbreeding, including the received gains in weight, milking capacity, we have become convinced of its advantage. The advantage of crossbred growing sheep has to do with a degree of expression of heterosis effect. The quantity of products derived from crossbred lambs was significantly greater at fewer costs for its production.
