In an experiment with 50 cows with milk yield about 5000 kg at the preceding lactation split into two groups during winter period was studied the effect of additive of niacin (6 g/cow/day), 7-10 days before calving until 30-th day after calving on consentration of ketone bodies, lactate and glucose in the blood.Animal were fed same rations roughage and concentrate with the only difference that experimental cows received 6 g niacin/cow/day with the protein-bioconcentrate mixture.It was found that additional niacin influencing the concentration of ketone bodies, lactate and glucose in the blood.Compared to control cows the concentration of (beta-hydroxybutyrate decreased after calving with 5.5% (0.213; 0.201 mmol/l), and total ketone bodies - with 4.5% (0.273; 0.261 mmol/l; P0.05).At the conditions of experiment the influence of niacin on concentration of glucose was not clearly expressed, but obviously it was positively influenced.
