Relationship of the chemical composition of milk with the values of diagnostic indicators of metabolism intensity

It was found that, in accordance with the selected analysis criteria, in the studied animal population in 17.05 % of cows, FPR corresponded to the optimal values, and in 82.95 % it deviated to the lower side and amounted to 1.10 or less. FPR tended to decrease as the milk productivity of animals increased, and increased as soon as the milk productivity of animals began to decrease in the dynamics of milk days. In the group of animals with FPR 1.10 or less, the content of BHBA in milk significantly (by 80.0 %, p
