棉籽粕脱毒技术及其在畜禽生产中的应用

Detoxification technology of cottonseed meal and its application in livestock and poultry production

棉籽粕中粗蛋白的含量较高,是较好的蛋白饲料资源之一。但棉籽粕中的游离棉酚(FG)等抗营养因子限制了棉籽粕的应用,利用物理、化学、生物等脱毒方式可显著降低棉籽粕中FG含量,提高其饲用价值。文章对棉籽粕的营养特性、常用的脱毒方法及其在畜禽生产中的应用情况进行综述,以期为棉籽粕在畜禽生产中的合理利用提供参考。

The content of crude protein in cottonseed meal is relatively high, and it is one of the better protein feed resources. However, the free gossypol(FG) and other anti-nutritional factors in cottonseed meal limit the application of cottonseed meal. The poisoning method can significantly reduce the FG content in cottonseed meal and improve its feed value. The article summarizes the nutritional characteristics of cottonseed meal, common detoxification methods and its application in livestock and poultry production, in order to provide references for the rational use of cottonseed meal in livestock and poultry production.
