短链脂肪酸的生物学功能及其对猪肉品质的影响
Biological Functions of Short-chain Fatty Acids and Its Effect on Meat Quality in Pigs
摘要
Abstract
Short-chain fatty acids(SCFAs)are metabolic byproducts produced by gut microbiota through the fermentation of dietary fiber and other indigestible carbohydrates,which possess a variety of biological functions,including antimicrobial,anti-inflammatory,and anticancer activities,as well as the regulation of gut microbial composition.SCFAs not only interact with gut microbiota,facilitating inter-microbial communication and modulating the intestinal immune system to enhance barrier function and promote intestinal homeostasis,but can also act as microbial metabolites that cross the gut barrier and exert systemic effects on the host organism.Pork accounts for approximately 30％of global meat sales.With growing consumer demand for high-quality pork,producing premium pork products with distinctive flavor and superior meat quality has become a major focus in the swine industry.In animal husbandry,SCFAs have mainly emphasized their roles in promoting intestinal health and regulating immune function.As the understanding of the relationship between gut microbiota and body metabolism deepens,the mechanisms by which SCFAs,as an important medium of the gut-muscle axis,influences meat quality in pigs through regulating muscle fiber development and intramuscular deposition are becoming increasingly clear.This review summarizes the biological functions of SCFAs,and their relationship with the characteristics of meat quality in pigs,and current research on how SCFAs regulate muscle fiber transformation and intramuscular fat deposition through gut-muscle axis,so as to provide insights for studies and applications of SCFAs regulating meat quality in pigs.关键词
