摘要
菜籽饼粕的粗蛋白质含量高,氨基酸组成合理,是一种优质的植物性蛋白质饲料资源.然而,菜籽饼粕中的抗营养因子,如硫苷、单宁、植酸、芥子碱等对猪的养分消化吸收和生长有负面影响.为提高菜籽饼粕的营养价值,原料常经过包括物理、化学和生物的方法进行脱毒,其中生物脱毒法的研究应用较为广泛,如采用酶法和发酵法去除抗营养因子,降低纤维素含量,提高菜籽饼粕的适口性和营养价值.本文主要就菜籽饼粕的营养价值、抗营养因子、脱毒方法以及其在猪饲粮中的应用进行综述,为菜籽饼粕的高效资源化利用提供参考.
Abstract
Rapeseed cake meal is rich in crude protein with a well-balanced amino acid profile,making it a high-quality plant-based feed protein resource.However,the presence of anti-nutritional factors in rapeseed cake meal,such as glucosinolates,tannins,phytic acid,and erucic acid,has adverse effects on nutrient ab-sorption and growth in pigs.To improve its nutritional value,raw materials are commonly detoxified using physical,chemical,and biological approaches.Among these,biological detoxification methods,such as en-zyme treatment and fermentation,have been widely studied and applied to reduce anti-nutritional factors,lower fiber content,and improve the palatability and nutritional value of rapeseed cake meal.This review provides an overview of the nutritional value of rapeseed cake meal,anti-nutritional factors,detoxification methods,and its application in pig feed,aiming to facilitate the efficient utilization of rapeseed cake meal resources.[Chinese Journal of Animal Nutrition,2024,36(7):4103-4115]
