Biochemical composition of blood in fresh cows under the influence of stimulation of mammary gland

The influence of mechanothermoelectricstatic stimulation of udder at the period of preparation for calve using of the «Kuban'-4» device on blood biochemical composition of pure breed fresh cows of the Airshir breed and hybrid F1 (Red Steppe × Holstein) was studied. It was shown, that after stimulation the blood biochemical composition was changed in hybrid animals greater than in pure breed ones. It suggests about the high adaptivity of hybrids. The increase of intensity of protein metabolism in animals organism during the udder stimulation promote to rise of milk productivity of fresh cows.
