Studying the metabolism of horses when feeding them zeolite-sapropel feed additives in the conditions of Yakutia

Abstract

The article presents the results of study on the effect of zeolite-sapropel feed additives on the metabolism of mares in Central Yakutia. Three groups of horses were formed to conduct scientific experiments. These groups were selected based on the principle of analogues, which took into account age, body weight and fatness. The control group got a basic ration. The experimental groups got a zeolite-sapropel feed additives to the basic ration in doses of 0.5 g of zeolite per kg of body weight with 200 and 300 g of sapropel. The study of the absorption of nutrients determined the effect of zeolite-sapropel feed additives on the intensity of nutrient uptake. Animals of the I and II experimental groups digest better: dry matter by 0.89% and 1.10%, organic matter by 0.90% and 1.17%, crude protein by 1.07% and 1.48%, crude fat by 2.16% and 5.08%, crude fiber by 1.70% and 2.43%, nitrogen-free extractives by 0.63% and 0.77%. Thus, the studies have shown that mares of the experimental groups fed with zeolite-sapropel additives, better use nitrogen, calcium and phosphorus. The studies have proved the effectiveness of using zeolite-sapropel feed additives when feeding mares in Yakutia.
