The effectiveness of organomineral feed additives from local raw materials in feeding young horses in Yakutia

Abstract

The article presents data on the study of the effect of organomineral feed additives based on sapropel and zeolite in combination with mineral salt while feeding young horses in the Far North of Yakutia. The research was carried out on young horses of the Yan type of the Yakut breed. Three groups of experimental young horses were selected. Clinically healthy animals were approved for scientific experiment. The research program included the study of growth and development for individual periods of cultivation, assessment of nutritional value of diets by groups, the study of the blood morpho-biochemical composition to determine the effect of feed additives on the animal physiology. Experiments have shown that animals consuming organomineral feed additives grew more intensively and surpassed their peers in all periods of rearing. Thus, at 5 months of age horses from II and III experimental groups surpassed others by 0.78% and 0.50%, and upon reaching 6 months of age this indicator was equal to 2.37% and 1.55%. In total, during the experiment the animals from the experimental groups exceeded the test group by 10.92% and 6.21% in terms of live weight. This is most noticeable in the average daily gain in live weight. Therefore, at the age of 4-5 months the experimental groups grew more intensively than the test group by 8.68% and 3.77%; in the 5-6-month age the result was similar (by 13.16% and 8.65%). It means that feeding organomineral additives to young horses contributed to a significant increase in live weight and to the improvement in the blood morpho-biochemical composition.
