Studying the influence of natural physical activity on animal productivity - actual direction of scientific researches

This article summarizes the results of the research at the Department of Standardization, Metrology and Technology of livestock production, which were already obtained more than 30 years. For achieving the aim of our study we were using these parameters: productivity of animals (rhythmic yield of cows and the chemical composition of milk, the growth of heifers), digestibility of nutrients and energy consumption for milk production, fertile cows and heifers and cows blood chemistry.

rhythm milk yield, chemical composition of the milk, the growth of heifers, fertility of cows and heifers, calves safety, blood biochemical indicators of cows, natural physical indicators activity, and correlation coefficient
