犊牛断奶应激与营养调控研究进展
Research Progress on Weaning Stress and Nutritional Regulation in Calves
摘要
Abstract
The weaning of calves is a crucial turning point in their growth and development,and it is also the peak period for stress occurrence.Weaning stress can damage the growth performance and health condition of calves,leading to a decline in the production efficiency of the farm and restricting production efficiency.Weaning stress is a physiological and behavioral response that calves generate during the adaptation to the environment and the change of feed.It can cause growth retardation and a decline in the body's immunity,thereby increasing the risk of illness.In-depth analysis of the influence mechanism of weaning stress and nutritional regulation measures has important guiding significance for production practice.This article systematically expounds the effects of weaning stress on the growth and development of calves,feed digestion and absorption,gastrointestinal flora,and gastrointestinal barrier.On this basis,targeted scientific nutritional regulation measures are proposed,and the mechanism of action of vitamins,minerals,plant extracts,and probiotics in alleviating weaning stress is summarized.Adding nutritional additive supplements reasonably before and after weaning can effectively promote the growth and development of calves,improve their health,and thereby reduce the negative impact caused by weaning stress,aiming to provide theoretical basis for the optimization and promotion of early weaning technology for calves.关键词
