STUDY OF MEAT AND DAIRY PRODUCTIVITY OF LAMANCHA AND ZAANENSKAYA GOAT BREEDS

Abstract

Goat breeding is a topical trend in agriculture at the present time. Goat milk is in demand because of its dietary properties, and goat meat also has high taste. However, the development of both dairy and beef goat breeding in Russia on large farms is insignificant. To develop recommendations on the technology of breeding goats in the Rostov region, studies of the indicators of meat and dairy productivity of the most popular breeds of Lamancha and Zaanen goats were presented at the FSBEI VO Donskoy State Agrarian University on the basis of IP Panchenko. It has been established that the experimental goats can be attributed to mid-season animals, and the content of internal fat in the carcasses of goats increases with age. In the meat of young Lamancha goats, the protein and dry matter content is higher, therefore, young Lamancha goats are superior to those of the Saanen breed. Goats of the Saanen breed surpass the Lamancha goats in milk yield in 305 days and have higher average daily milk yields, but the Lamancha goats have superiority in milk fat yield in 305 days of lactation. Also, the milk yield of goats of the Saanen breed for 20 days of lactation is greater than that of goats of the Lamancha breed. To increase the production of goat meat, it is necessary to practice fattening super-repair young Lamancha goats from 6 to 8 months of age. In order to obtain competitive, high quality goat meat, young animals should be intensively raised, fattened and slaughtered for meat between 7 and 10 months of age. For dairy goat breeding, it is more effective to use Saanen goats for purebred breeding.
