Biochemical status of highly productive cows under different housing

The purpose of the research is to study the biochemical composition of blood of highly productive cows in different lactation periods and under different ways of housing. The research has been conducted in the framework of theme no. 157.1 “Studying the feeding of highly productive cows given the biochemical status of the animal and the quality parameters of milk under different housing in conditions of the European North of the Russian Federation”. The task is to consider the biochemical composition and biochemical parameters of the blood of highly productive cows under different housing. The relevance of the work is due to the need to assess the state of metabolic processes in animals’ organism contributing cows’ high milk productivity. The values of parameters that make up the biochemical status of highly productive cows’ blood under different housing are described. The novelty and practical significance of the research lies in the use of indicators characterizing the intensity of metabolism to assess the nutritional status of dairy cows.
