CHANGE IN PHYSIOLOGICAL INDICATORS OF COWS OF THE GOLSHTIN BREED BY SEASONS OF THE YEAR

The article describes data on the study of physiological parameters of Holstein cows by seasons, in the diet of which hydroponic green feeds are included. It was found that the inclusion of hydroponic green feeds in the diet of cows did not have a noticeable effect on physiological parameters. Body temperature, pulse, respiration have changed depending on the seasons within the limits of physiological norms, which allows us to judge the good fitness of Holstein cows to the conditions of our Republic.
