Influence of maintenance's conditions on parameters of protein and nitrogenous metabolism in grey ukrainian breed heifers
Ò. Spitsyna, V. Gryban
The results of research of indicators of the protein and nitrogenous metabolism, spent on Ukrainian grey breed heifers 13-14 monthly age at their stall and pasture-camp keeping are resulted in this article. It is established that at pasture-camp keeping system intensity of protein synthesis increases, liver functional activity increases to what testifies concentration of nitrogen filtrate and urea in their blood and higher activity of aminotransferases; the nucleic metabolism increases and higher an effective utilisation of tissues energy resources is marked.
