Physiological increase in blood glucose levels in holstein cows during the transition period (review)
Abstract
The transition period in high-yielding Holstein cows is characterized by significant metabolic and endocrine changes, particularly in blood glucose levels. Despite the generally accepted tendency toward hypoglycemia in the early postpartum period, the literature describes cases of physiological increases in glucose concentrations caused by the stress response, endocrine regulation, and adaptive mechanisms.
This review systematizes current literature on the physiological mechanisms of increased blood glucose levels in Holstein cows during the transition period, including the role of cortisol, catecholamines, insulin resistance, and gluconeogenesis.
