Аннотація: It was found that ethological traits and indicators of milk production of cows are characterized by a medium and high degree of phenotypic variability. With age, cows rested less time lying down, but spent more time eating feed. Analyzing the factor dependence of the level of milk yield per lactation in cows, it was found that the greatest influence on the formation of this trait is age, the strength of which is 74.5%, and the share of the influence of unaccounted factors was 25.5%. With the increase in milk production, there is a tendency to reduce their reproductive function. This feature should be used in the breeding process with livestock. An in-depth study of the causes of variability in farm animals will allow us to assess the adequacy of their habitat and develop the most rational and economical systems of interaction between the organism and technical means, feeding factors and other realities of industrial technology. Ethological research will make it possible, first of all, to create optimal conditions for keeping both in industrial livestock farms and on traditional farms, to find ways to increase cow productivity in specific feeding and housing conditions. Animals bred with ethology in mind have a calm disposition, their behavior can even be controlled, and they are usually characterized by high milk and meat production and efficient feed use. Skillful application of ethological techniques in animal husbandry can increase the productivity of cattle. The reaction of high-yielding cows to paratypical factors is ambiguous and is always accompanied by behavioral changes, reduced milk production, deterioration in product quality, increased morbidity, reduced duration of productive use, and premature culling from the herd. Finding out the behavioral characteristics of high-yielding cows will make it possible to optimize the methods of their maintenance, feeding, and operation and ensure high milk production with high milk quality and herd safety.
