Abstract
Sheep breeding has great national and economic importance for the Republic of Dagestan. The creation of optimal feeding conditions for sheep signifi cantly accelerates the process of improving their productive characteristics and the quality of the products obtained. The feed factor promotes the growth of wool and improves its quality in fi ne-wooled sheep breeds. The study of the influence of biologically active substances on economically useful traits of sheep is an urgent task. The purpose of the research was to study the infl uence of the new probiotic feed additive Enervit in the rations of young sheep of Dagestan mountain breed on wool productivity and its quality. As a biologically active additive in the ration of young sheep of Dagestan mountain breed a probiotic feed additive Enervit was used consisting of a compound of mineral additives such as chalk, table salt, feed diammonium phosphate, calcium sulfate, copper sulfate, zinc sulfate, manganese sulfate and cobalt chloride. The experiment was carried out by the method of groups on young rams with an average live weight of 26,2 kg. The sheep of the control group received a ration without the introduction of the feed additive Enervit, and to the animals of the 1st experimental group were added the drug in the amount of 10, 15, 20 g/head/day, depending on the age of 4, 8 and 12 months. The young rams of the 2nd experimental group were given Enervit, respectively, for these age periods 13, 24 and 26 g. Based on the indicators of the amino acid composition of the wool of sheep of the experimental groups, its best quality was characteristic of animals that received the feed additive Enervit in the amount of 10, 15 and 20 g/head/day at the age of 4, 8 and 12 months, respectively. The addition of the drug to the rations of Dagestan mountain sheep in such the amount leads to an improvement in the metabolism in the body of animals, as a result of which the quality indicators of the wool of the sheep of the 1st experimental group increased.
