The Effectiveness of Unconventional Feed Additives at Feeding Cattle in Conditions Yakutia

The article is devoted to the question of the possibility of using non-traditional feed additives in feeding young cattle in the Republic of Sakha (Yakutia). In conditions of macro- and microelements deficiency in feed in the permafrost zone, the use of sapropel, zeolite and mineral salt is relevant. In this regard, studies have been organized to determine the optimal norms for the inclusion of feed additives in the rations of cattle. In accordance with the main goal of the research, we studied the indices of the digestibility of nutrients rations and the dynamics of the live weight of experimental animals when fed with non-traditional feed additives. The inclusion of feed additives in the ration of cattle made it possible to improve the digestibility of nutrients for protein by 0.95 and 2.22%, fat by 3.29 and 3.7%, fiber by 0.61 and 0.73%, nitrogen-free extractive substances by 0.98 and 1.46%. Analysis of the live weight data showed that the experimental groups were superior to the control group in all periods of rearing. At the end of the experiment, these groups were heavier than their peers by 3.30 and 5.47%. The inclusion of non-traditional feed additives contributed to an increase in the average daily milk yield of first-calf heifers by 9.07 and 7.58% and an increase in the content of fat and protein in milk. Therefore, the inclusion of non-traditional feed additives in the ration of cattle improves metabolism and productivity.
