摘要
日粮淀粉来源、颗粒大小、颗粒形态、分子结构、结晶度及直支比影响着断奶仔猪的养分消化率和生长性能。其中适宜的直链淀粉与支链淀粉比,会改善畜禽小肠的形态结构和肠道环境,提高小肠的消化吸收能力,从而提高饲料的利用率。本文对日粮淀粉来源及直支比对断奶仔猪养分消化率和生长性能的影响进行了综述,旨在为养猪生产提供适宜的淀粉来源及直支比。
The source,particle size, particle morphology,molecular structure,crystallinity and amylose/amylopectin of diet starch affect the nutrient digestibility and growth performance of weaned piglets.The proportion of amylose/amylopectin could improve the intestinal morphology and intestinal environment in livestock and poultry.It also could improve the small intestinal digestion and absorption ability,thus improve the utilization rate of feed.The influences of dietary starch sources and amylose/amylopedtin on nutrient digestibility and growth performance in weaning piglets were reviewed in this paper.The aim was to provide snitable starch sources and amylose/amylopectin for pig production.
