棉粕的营养组成及其在畜禽生产中的应用

棉粕是棉籽经过压榨、浸出等工艺得到的一种微红色或黄色的颗粒状物品，其粗蛋白的含量可达40%以上，仅次于豆粕，是优良的植物蛋白源之一。因此，常被人们当做饲料原料应用于养殖业中。但因棉粕中含有很多抗营养因子，如游离棉酚、单宁、植酸、环丙烯脂肪酸等，会对动物产生一定的毒害作用，使得棉粕在动物中的利用受到限制。对棉粕的营养组成及其在畜禽生产中的应用进行了综述，以期为棉粕在畜禽生产中的合理利用提供参考。

Nutritional Composition of Cottonseed Meal and Its Application in Poultry and Animal Production

Cottonseed meal, the light red and yellow granular articles, is obtained from cottonseed by processing technics of press and extraction. The crude protein content of cottonseed meal is second only to soybean meal and reaches above 40%. Accordingly, cottonseed meal is one of the good resources of plant protein and is widely applied in livestock breeding industry as feedstuff. However, there are a series of anti-nutritional factors in cottonseed meal, including free gossypol, tannin, phytic acid, cyclopropane fatty acid, etc. These anti-nutritional factors show toxic effect to animals, which constricts the application of cottonseed meal in animals production. With the goal of providing references for the rational application of cottonseed meal in animal production, we reviewed the nutritional composition of cottonseed meal and its application in poultry and animal production.
