Metabolic processes Indicators in chickens of different productivity directions and their relationship with the composition of muscle tissue

Abstract

The object of our research was blood and muscle tissue samples of the breast and thigh, taken from birds at the age of 63 days of the following groups: group 1 - egg productivity (cockerels, Russian White breed, n=28), group 2 - meat and egg productivity (cockerels of a cross between Russian white and Cornish breeds, n=148 - blood, hens n=81 and cockerels n=148 - muscle tissue), group 3 - broilers (cockerels, cross Ross-308, n=9). As a result of the studies, we have established differences in the content of metabolites of carbohydrate-lipid and mineral metabolism in chickens of egg, meat-and-egg directions of productivity and broilers. The results obtained will serve to collect the database of biochemical parameters of poultry blood and further develop reference intervals for birds of various genotypes, which will be useful in terms of monitoring the health status of poultry and obtaining high-quality poultry products. Correlation relationships between biochemical blood parameters and indicators of metabolic processes were determined, and differences in the obtained values between poultry groups in terms of productivity were established. The data obtained open up prospects for expanding the range of biochemical parameters and their use in order to obtain high-quality livestock products.
