Abstract

As an integral and important part of the livestock industry, interest in dairy goat farming has been growing steadily in recent years. At the same time, the milk productivity of goats is largely determined by the balance and completeness of the diet. Our study aimed to determine the effect of adding chlorella suspension in combination with a probiotic to the diet of Saanen goats on the quality characteristics of the milk obtained during the milking process. The material base for the experimental study was the goat breeding farm of the Lukoz agricultural holding in the Sernursky district of the Republic of Mari El, where, according to the principle of analogs, dairy goats at the stage of the second lactation were divided into 3 groups of 20 heads each. The control group was kept on a normal diet. Goats belonging to the experimental groups received chlorella suspension daily with water at the rate of 40ml per animal. The second experimental group additionally received the probiotic Bacillus subtilis at 10g per animal. Every 10 days, milk productivity was analyzed through control milking, and blood and milk samples were taken for laboratory analysis. The study showed a significant increase in the number of erythrocytes and hemoglobin levels in the blood of the experimental groups of animals. In addition, an increase in the concentration of glucose, total protein, albumin, and globulins in the blood serum was observed, which indicates the activation of metabolic processes, including carbohydrate metabolism. Adding chlorella suspension to animals’ diets benefits the functioning of the body’s immune system. The phagocytic activity of neutrophils in the body indicates the animal’s immune status. The use of chlorella suspension in goat diets helps not only strengthen the immune system but also increases the milk yield of animals. With these supplements, goats produce more milk, and also the total protein, casein, fat, and mineral content of the milk are increased. This is an important factor for dairy producers, as it improves the quality and value of the resulting product.
