The authors conducted studies on broiler chickens, cows, pigs, sheep of various crosses and breeds, in order to identify the species and breed characteristics of the functioning of blood ATPases (erythrocyte membrane of blood) and ATPases of products (membrane of fat globules of milk, membrane of structural components of muscle tissue. The results obtained have shown that the species identity of livestock has a significant (P 2 +, Na+, K+ -, Mg 2 + - and Na+, K+ -ATPases of the erythrocyte membrane and structural components of the livestock products. The two-factor (the livestock species and breed) the analysis of variance carried out by the authors has proved with a high degree of reliability (P 2 +, Na+, K+ -, Mg 2 + - andNa+, K+ -ATPases of the erythrocyte membrane is determined by the livestock species with a high degree of confidence (P 2 +, Na+, K+ -, Mg 2 + - and Na+, K+ -ATPases has been detected.
