EFFICIENCY OF GROWING MEAT-WOOL FIELDS DEPENDING ON THE TONNAGE OF WOOL

Abstract

In the article, based on the conducted research, considers the expediency of using wool fineness indicators in the selection process when growing meat-wool breeds. Due to the lack of a comparative analysis of animal husbandry, experimental groups were formed conditionally and distributed according to the total number of herds. The first group of experimental animals included yaks with the thickness of wool fibers – 23.1–25.0 μm or 60th quality; to the II group with an average fiber diameter of 25.1–27.0 μm or 58th good quality;The III group consisted of ditches with a greater thickness of wool fibers – 27.1–29.0 μm or 56th good quality. In order to study the effectiveness of using fodder in production, three model groups of 10 head each at the age of 12 months were formed. It was established that during the 60-day growing period, the indicators of absolute, average daily and relative growth in pits of II and III groups were higher. Feed costs per 1 kg of body weight gain amounted to 11.4 units in the first group and 1282 g of digestible protein, in the II and III groups, respectively, 10.3 units. and 1166 g and 10.4 k. units. and 1169 g of digestible protein. Conducted studies have shown that the yaks with the tone of wool of the 56th quality are characterized by higher indicators in terms of live weight, development and wool productivity, which indicates their better adaptation to the natural and climatic conditions in which the farm is located.
