有机铬的生物学特性及其在猪营养中的应用
Biological properties of organic chromium and its application in pig nutrition
摘要
Abstract
Chromium is a bioactive trace element whose nutritional essentiality and physiological functions remain controversial.It may participate in regulating glucose and lipid metabolism,alleviating heat stress,and modulating meat quality.Organic chromium can affect glucose utilization,gluconeogenesis,and lipid metabolism through insulin signaling,the AMP-activated protein kinase energy-sensing system,and key metabolic enzymes.Under heat-stress conditions,chromium may improve endocrine homeostasis and alleviate inflammatory and oxidative damage by enhancing insulin sensitivity,supporting the glutathione antioxidant system,and inhibiting protein glycation.However,its effects vary with chromium source,supplementation level,pig genotype,physiological stage,and rearing environment.This review summarized the biological properties of organic chromium and its effects on stress resistance,growth performance,carcass traits,and meat quality in pigs,providing a theoretical basis and practical guidance for optimizing its application in pig nutrition.关键词
