UTICAJ APLIKACIJE NIACINA NA VREDNOST NJEGOVIH VITAMERA U KRVI KRAVA U RANOJ LAKTACIJI

Abstract

Vitamin niacin is of great importance for energy metabolism. Physiological niacin is incorporated into the coenzyme nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). The aim of this study was to determine the concentration of NAD and NADP in the blood of cows during the application of niacin in the peripartum period. The value of these vitamins depends on the peripartum week, regardless of the constant exogenous source of niacin.
