AUTONOMOUS NERVOUS REGULATION OF THE BIRD'S BODY ACCORDING TO TYPOLOGICAL FEATURES

Abstract

Studies of the typological features of the autonomic nervous system in chickens revealed the lowest fashion indicators in combination with the highest values of heart rate in sympathicotonic chickens compared to normo- and vagotonic chickens. At the same time, vagotonics had a tendency to the highest values of fashion, to lower values of fashion amplitude and heart rate. At the same time, in chickens with a balanced type of vegetative regulation, lower average indicators of superoxide dismutase of 2.877 units of act./mg of hemoglobin were found, which are compensated by a higher activity of other investigated enzymes of antioxidant protection - catalase and glutathione peroxidase, which indicates a balance of enzymatic activity in chickens with a predominance normotonic tone of the ANS. In vagotonic chickens, a tendency to increase the average indicators of the activity of all investigated enzymes of the antioxidant system compared to normo- and sympathic chickens was revealed. At the same time, the average value of SOD activity in sympathicotonic chickens is statistically higher than that of normotonic chickens by 8.7%.
