КОНВЕРСИЯ ПИТАТЕЛЬНЫХ ВЕЩЕСТВ И ЭНЕРГИИ КОРМА В МЯСНУЮ ПРОДУКЦИЮ ПРИ ОТКОРМЕ МОЛОДНЯКА КАЛМЫЦКОЙ ПОРОДЫ В УСЛОВИЯХ ЯКУТИИ

Abstract

The article presents the results of studies of the bioconversion of nutrients and feed energy into meat products when fattening young Kalmyk breed in Yakutia. The studies were carried out on the basis of the SCHPK Soloyun Megino-Kangalassky region. The experiment was organized on Kalmyk gobies fed from 17 to 18 months of age. For the experiments, 2 groups of animals were formed, which were divided into control and experimental groups. The control group consumed the main diet, the experimental group additionally consumed 200 g of Suntarsky zeolite per head. The main diet of animals by structure consisted of meadow hay 46%, haylage – 22% and mixed fodder 32% or 11.95 ECU per day. During the experiment, the live weight of the animals was almost identical. At the end of fattening, the animals of the control group yielded to the bulls of the experimental group by 3.5%. It was found that the gobies of the experimental group had higher indicators of meat productivity, which affected bioconversion. The analysis showed that the control group of bulls yielded to the experimental group in terms of pulp by 26.9%, in the deposition of food protein by 13.6%. The conversion rate of protein into food protein in the control group was 12.0%, and in the experimental group the indicator was 21.3%. The yield of dietary protein in the control group was 8.08 g, which is 33.6% less than in the experimental group. Thus, the calculation of bioconversion showed that the animals of the experimental groups, which additionally consumed Suntarsky zeolite, had a higher ability to transform nutrients and feed energy into meat products.
