ПРОИЗВОДСТВЕННО-ТЕХНОЛОГИЧЕСКАЯ ОЦЕНКА ВЫРАЩИВАНИЯ БАРАНЧИКОВ КАРАЧАЕВСКОЙ ПОРОДЫ РАЗНЫХ МЕСЯЦЕВ РОЖДЕНИЯ

Abstract

Meat sheep breeding got a big popularity in recent years, which one of the main ways is production of high quality mutton with least possible working and physical resources. One of the reserves of expansion of output is the use of different processing methods, such as production and sale of lamb meat in birth year with account for lamb birth period. The research aim is to study growth characteristics and feed efficiency by liveweight gain of ram hog of Karachai breed, born in different months- February, March and April. Research for the study of growth characteristics and feed efficiency by liveweight gain on ram hogs of Karchai breed was carried out in conditions of submontane zone of the Kabardino-Balkaria Republic. The research object is ram hogs of Karachai breed. During the research analytical, common zoocultural and biometric techniques were used. Lambing ewes in February – March period gave the edge on offsprings in live weight parameters, daily live weight gain and feed efficiency by products. By the end of their superiority over ram-hogs of April birth month was according to liveweight 3,2-4,7 kg (Р>0,999), and according to average daily growth for all the production cycle – 12-17 g (Р>0,999). Production of lamb meat from ram hogs of February- March birth period was less expensive which had for 0,61-0,77 EFU and 61-79 g of digestible protein lower, was less expensive. Lambing ewes in February and March provides the obtainment of more constitutional strong offsprings, which predominate herdmates of April birth according to growth parameters and feed efficiency.
