HOMEORETSKA REGULACUJA METABOLIČKIH FUNKCIJA KOD KRAVA U PERIPARTALNOM PERIODU

Abstract

The aim of this paper is to describe complex homeoretic and homeostatic mechanisms in dairy cows during the peripartum period. The endocrine system has a key function in regulating the adaptation of metabolism during the peripartum period. Homeoresis represents the functioning of the endocrine system and metabolism in conditions when the organism must primarily provide certain physiological processes, such as fetal growth or lactation. Then the function of all tissues is adjusted to the new situation. Homeoretic hormones (growth hormone, prolactin, glucocorticosteroids, thyroid hormones, insulin, glucagon and leptin) in dairy cows in the peripartum period play a key role in maintaining high lactation and maintaining cow health.
