白藜芦醇的生物学功能及其在动物生产中的应用

The Biological Function of Resveratrol and Its Application in Animal Production

白藜芦醇是一种含有茋类结构的天然非黄酮类多酚类化合物,具有多种生物学功能:可抑制和清除体内过量的自由基,激活机体抗氧化酶系统,发挥抗氧化功能;通过调控一系列炎症或抗炎通路,降低机体内炎性因子表达,降低炎症反应。白藜芦醇还具有调节糖脂代谢、保护心血管、抗癌、抗病毒等重要生物学功能,且具有安全高效、无残留、不产生耐药性的优点,在动物生产中的应用具有广阔的应用前景。动物试验表明,白藜芦醇能提高肉鸡平均日增重、平均采食量,降低料重比;提高育肥猪肉品质,增加背最长肌pH 24 h、红度、粗蛋白质和肌红蛋白含量,还可降低24 h后肌肉亮度、剪切力、滴水损失、背膘厚度;提高动物机体内抗氧化酶活性;降低炎性因子的产生,增强机体免疫;改善肠道菌群组成和肠道黏膜形态;抑制癌细胞的生成。本试验针对白藜芦醇生物学特性、生理功能及其在畜禽生产中的应用现状进行综述,旨在为其在畜禽生产中的应用提供参考依据。

Resveratrol is a natural non-flavonoid polyphenolic compound containing a quinone structure.It has various biological functions,including inhibiting and eliminating excess free radicals in body,activating the body’s antioxidant enzyme system and exerting antioxidant function.By regulating a series of inflammatory or anti-inflammatory pathways,it can reduce the expression of inflammatory factors in the body and the inflammatory response.Resveratrol also has important biological functions such as regulating glycolipid metabolism,protecting cardiovascular,anti-cancer,anti-virus,etc.It has the advantages of safety,high efficiency,no residue,no drug resistance,and has broad application prospects in animal production.Animal experiments show that resveratrol can increase the average daily gain,average feed intake,and feed to gain ratio of broilers.It also can improve the quality of fattening pork,increase the longissimus dorsi muscle,pH 24 h,redness,crude protein and myoglobin The compound can also reduce muscle brightness after 24 h,shear force,drip loss and backfat thickness,increase antioxidant enzyme activity in animal body,reduce inflammatory factor production,enhance immunity and improve intestinal flora composition and mucosal morphology,inhibits the formation of cancer cells.The authors will review the biological characteristics,physiological functions of resveratrol and its application status in order to provide reference for its application in livestock and poultry production.
