title: [The connection of adrenal function to nutritional factors and milk productivity in ruminant animals].
abstract: In this paper the literature and experimental data about ruminant's adrenal function in the connect with feeding level, ration structure and lactation are generalized and systematized. It is shown, that the adrenal secretion and either glucocorticoid, or katecholamine metabolism can be changed in the dependence on the alimentary factors. When the animals feeding is not adequate physiologically, increased cortisol secretion is necessary for supporting of glucose level in the normal value, what leads to increased loading to the adrenal cortex and is accompanied by redistribution of this hormone between plasma and erythrocytes. The hypothesis explaining the received results is advanced. The ability of the endocrine indexes utilization for the estimation of physiological adequately of rations is discussed. The role of adrenal hormones in the regulation of the mammary gland supplying with the milk precursors, and the mechanisms of these hormones action (either positive, or negative) to the organism lactation function are studying.
