The study describes the characteristics of protein metabolism in turkeys of different genotypes and age. It is established that poults during industrial cultivation were physiologically healthy, and the studied parameters fluctuated within normal limits. At the same time, the magnitude of the blood parameters depends on the age of the bird and the genotype determined by both the breed and crossing. The protein metabolism intensity determining the concentration of the total protein and its fractions in the blood of poultry, the activity of transamination enzymes (AlAT, AsAT) does not so much depend on age, but on the birds genotype. The highest level of protein parameters is found in the blood of heavy cross Hybrid Converter. At the same time, the rate of growth and development of their body is associated with the exchange of albumin and the ways of using free amino acids to cover its energy consumption. Therefore, turkey poults of this cross are superior to their analogues in terms of albumin (by 9.54%), activity of AsAT (by 1.61–6.93%) and AlAT (by 2.77–5.23%).
