06.00.00 Agricultural sciences
Description
The study of the productive qualities of crossbred offspring from different breeding combinations and identifying the most effective ones providing the maximum increase in the production of high quality lamb while reducing its cost is an important problem and is essential for further development of methods of creating a new type of precocious meat and wool sheep. In the Rostov region in the result of the establishment of populations of meat-wool sheep there are several groups of animals with different characteristics and hereditary inclinations. As the base of the work there is a method of mating and breeding of sheep of the desired type. The article presents the results of one of the fragments of a large complex work in which the possibility of using three-pedigree hybrids, created with the involvement of potential salskaya, edilbaevskaya and intense meat-wool breed, which is severokavkazskaya, to improve productive quality in the breeding of sheep. We have evaluated productivity and biological features of hybrids and proved the economic efficiency of their use in the production of mutton. We have given the results of the control slaughter and assessment of qualitative indicators of the meat of young sheep. The set of indicators characterizing meat productivity and meat quality revealed that the superiority of the studied indicators remained for two - and three-bred cross cattle. Hybrids have a higher rate of growth and quality parameters of meat productivity. These options are simple and complex industrial crossing are promising and can be implemented and used on the farms of the zone of breeding Merino sheep. Thus, the use of crossbreeding gives an opportunity to convert a flock of sheep in the desired direction quickly. At the same time, three-pedigree hybrids better combine the valuable qualities of the used species
