The article presents the data on the study of age-related features of non-contagious pathology in broiler chickens, as well as the level of metabolic processes in liver of healthy poultry and poultry with diseases. The results of the studies indicate that in the conditions of an industrial enterprise specializing in meat poultry rearing, poultry mortality in different age periods ranged from 3 to 5 % of the total population. In the structure of the causes of mortality of broiler chickens from the 8th to the 15 th day, an increase in mortality from hepatopathies was registered, and by the 25 th day of life hepatosis was recorded in the bulk of the dead poultry. Biochemical monitoring of blood serum in poultry with signs of liver pathology revealed an increase in the level of ALAT, β-globulins, and the “inflammation syndrome” of the hepatic parenchyma was confirmed by a positive thymol test. Long-term consumption of feed contaminated with mycotoxins by broilers led to the deterioration in the health of the poultry, an imbalance in liver and the development of general metabolic disorders of the poultry organism.
