Study of the Influence of the Inclusion of Additives in the Food of Kаrakol Sheep on the Composition of Blood Plasma Proteins and Amino Acids

Abstract

The productivity of natural pastures, which are the main source of food for Karakol sheep, and the botanical and chemical composition of food undergo serious changes under the influence of climatic and seasonal factors. The productivity of pastures undergoes significant changes in years with favorable, moderately favorable and unfavorable climatic conditions, respectively. In accordance with the seasons, the consumption of food by cold animals, the supply of nutrients to their body varies significantly. Due to the insufficient supply of nutrients to the animal's body in the autumn-winter and early spring months, wool productivity and live weight decrease, as well as the deterioration of reproduction characteristics are observed. When the Karakol deer are fed with natural plants without additional nutrients throughout the year, the digestive processes in the large stomach undergo serious changes depending on the seasons or the physical conditions of the food consumed. The amount of food consumed by the karakol in the natural pasture feed, the digestibility coefficient of the nutrients in their content changed according to the level of nutrition and the amount of nutrients in the ration according to the seasons of the year. The coefficient of digestibility of nutrients, depending on the physical state of nutrients, was observed to be high in spring and summer and lowest in autumn and winter. The addition of additional nutrients to replace the missing nutrients in the feed ration of sheep allows increasing the digestibility of the nutritional components of the ration.
