Efficiency of Feed Utilization by Young Cattle in the Rearing of Feed Double

Abstract

Increasing the efficiency of animal feeding through the use of modern feed additives is one of the ways to solve this problem. Therefore, the evaluation of the effectiveness of the use of feed additives for the organization of full feeding of different sex-age groups of animals is relevant. The purpose of the research is to study the influence of the «Tripel BZ» feed additive on the use of feed in the body of young Ukrainian black-spotted dairy cattle at the age of 2-4 months, based on the analysis of feeding rations, using modern norms for feeding young cattle. In order to study the effectiveness of the use of the polymineral biologically active feed additive «Tripel BZ» in feeding young cattle in the PE «Kalinsky Klyuch» village. A scientific and economic experiment was conducted in Kalynya Kamianets, Podilsky district, Khmelnytskyi region. The material for the study was feed rations, which included the semi-liminal biologically active feed additive «Tripel BZ». A scientific and economic experiment was conducted on calves of the Ukrainian black-spotted dairy breed aged 2-4 months. For this purpose, two groups of similar Bugai cattle were selected, 12 heads each with an initial live weight of 72,5 kg according to the developed research scheme. At the same time, two groups of animals were formed: the first – control, the second – experimental. The young were kept in groups of 12 heads, untethered, in one room – the conditions of keeping were similar for both groups. At the same time, the animals of the first group were fed the basic diet, and the animals of the second group were given polymineral biologically active feed additive «Tripel BZ» as part of the basic diet. Analyzing the results of the conducted research should be noted. that the young animals that consumed rations with the «Tripel BZ» feed additive used feed more economically for the production of a unit of live weight gain, so it can be concluded about the feasibility of its use in feeding young cattle in the amount of 0,15 kg per day.
