The purpose of the work was to explore the indicators of functional state and function of protein synthesis of the cow liver within experimental fasciolysis, sensitized to atypical mycobacteria. Ten cows of black-and-white breed were selected for the experiments. Two groups consisting of five animals each were formed. The control group cows were clinically healthy. The animals of the experimental group were contaminated with mycobacteriosis and fascicular invasion. In the course of research, the rules for performing zootechnical experiments on the selection and maintenance of animal-analogues in the group, harvesting technology, use and accounting of consumed feed were followed. Being impacted by fascicular invasion, the cattle sensitized with mycobacteria demonstrated the suppression of the liver protein synthesis function, which manifests itself as a decrease in total blood protein, a decrease in the level of albumins and an increase in the level of globulins. According to the clinical manifestation of fasciolosis in the cattle sensitized with atypical mycobacteria, disease pathogens have a toxic effect on hepatocytes causing an increase in the permeability of the biological membranes of the cell membranes. The indicated changes lead to an increase in the activity of blood serum enzymes, in particular, aminotransferases (AsAT and AlAT) and alkaline phosphatase. High activity of AlAT and AsAT in the blood serum of the cows under experimental fasciolysis sensitized by atypical mycobacteria, indicates destructive processes in the liver that cause release of aminotransaminases from cellular organelles in the blood of the cattle. Thus, the results obtained indicate an increase in destructive processes in the body of the cows under experimental fascioliasis sensitized with atypical mycobacteria.

In the article are considered issues related to the study of the effect of cadmium on the body of birds, in particular laying hens. The effect of cadmium sulfate at doses of 2.0 and 4.0 mg/kg body weight on protein synthesis function and functional state of the liver were investigated of cross-laying Hysex white hens, of 78 weeks old. Three groups of chickens were formed: two experimental and one control groups. The laying hens of the experimental groups were subjected to a cadmium load. Laying chickens of the first experimental group were given cadmium sulfate at a dose of 2.0 mg/kg body weight. Laying chickens of the second experimental group were given cadmium sulfate at a dose of 4.0 mg/kg body weight. Laying chickens in the control group were in the normal diet without cadmium. Increased activity of aminotransferases, in particular alanine and aspartate aminotransferases in their serum of hens, was observed during cadmium binge drinking in doses of 2.0 and 4.0 mg/kg body weight, respectively. These changes indicate a violation of the functional state of the liver of laying hens under conditions of cadmium load. In the study of protein synthesis of the liver of laying hens under conditions of cadmium loading, it was found that cadmium sulfate in the above doses contributed to a significant decrease in the level of total protein by 14, 21 and 30 days of the experiment. The reduction of total protein in the blood of laying hens was due to a decrease in the level of albumin, which in the second experimental group, respectively, decreased to 28.16 ± 0.75%, whereas in the first – 29.62 ± 0.98%. In the study of the level of globulins, it is possible to increase this indicator in both experimental groups of poultry for 21 days. Drinking with water cadmium sulfate at a dose of 4.0 mg/kg body weight was associated with a more likely decrease in total protein and albumin than drinking cadmium sulfate at a lower dose.
