The influence of non-traditional feed additives on the productivity of horses in Yakutia

Abstract

The article presents data from the results of a study to determine the effectiveness of using unconventional feed additives for horse productivity in Yakutia. To conduct scientific experiments, 3 groups of horses of the indigenous Yakut breed were formed, 12 animals each. In order to enrich animal diets by macro and microelements, as well as to increase horse productivity in winter, the effect of zeolite-sapropelic feed additives on milk production and physiological state of animals was studied. In the process of conducting research, the following methods were used: biochemical, physiological, biometric and economic research methods. As a result of the research, it was found that the use of feed additives in feeding horses contributed to an increase in the milk yield of the experimental groups of mares 10.42% and 14.89%. At the same time, annual milk yield increased by 10.43% and 14.98%. It was found that the feed additive contributed to the improvement of the qualitative composition of milk, so for fat by 0.15% and 0.16% and protein by 0.19% and 0.32%. A study of the physiological status of animals found that the feed additives affected the biochemical composition of blood. An increase of albumin by 5.95% and 9.52%, globulin - by 1.37% and 3.42%, hemoglobin - by 1.74% and 3.20% was found in animals consuming feed additives. Analysis of the economic efficiency of the use of zeolite-sapropel feed additives in feeding mares has shown that in the experimental groups consuming feed additives, the profitability was 27.34% and 32.33%. Studies have proved the perspectivityof the use of organic mineral feed additives in feeding horses in the conditions of Yakutia.
