Efficiency of crossing Taurian type sheep of the Askanian breed with meat-fat and meat rams
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 99, Issue
Abstract
The study shows that young crosses produced in commercial mating have a much higher live weight at birth and also in all other periods of their life up to 8 months of age compared to the lambs of the Askanian fine-fleece breed. At the age of 8 months, the difference is 9.15-20.33% in favor of the cross generation. The indicators of meat productivity and quality testify to the possibility of economic use of crosses in the first year of their life. ... Analysis of the sheep breeding system on the leading farms of the Kherson region, our own research and economic calculations, as well as information obtained from literature sources allow us to give some suggestions on the sheep breeding system under the conditions of farms and individual peasant farming units: we are to carry out commercial mating of a part of a flock of fine-fleece sheep to meat-fat (fat-rumped) rams and those of other breeds that are not inferior to fat-rumped rams in meat quality traits. The remaining (best) part of the ewes is to be inseminated with the sperm of purebred rams of the maternal breed with the aim of obtaining a purebred young generation for maternal flock replacements. Young cross animals should be slaughtered before they reach the age of one year. The best crosses can be moved over to farms where crossbred sheep breeding will be in high demand.
