title: [Characteristic features of the function of the NAD+- and NADP+-dehydrogenase systems in the milk of cows with different levels of milk production].
abstract: The lactate[NAD]-, malate[NAD and NADP], glutamate[NAD]-, isocitrate [NADP]- and glucose-6-phosphate[NADP]dehydrogenase activity is determined to be directly proportional to the level of milk productivity in cows. NADP-dependent dehydrogenases have a more apparent positive correlation with the level of milk productivity in cows. This conclusion is confirmed by the analysis of a number of oxidizing and reducing substances of these enzymes in milk as well as by values of the [NAD+]/[NADH] and [NADP+]/[NADPH] ratio in it.
