Cottonseed meal has been used for many years as a protein supplement in animal rations. Due to a polyphenol pigment, gossypol, present in cottonseed meal, its use for swine has been limited. The tolerance of gossypol for monogastric animals depends upon age and species with older animals being less sensitive than younger animals. Swine are highly susceptible to gossypol poisoning, and signs commonly develop after one or more months of consumption. The use of iron salts in the ration appears to be antidotal, and lysine supplementation of gossypol containing diets appears to improve gain. Reproductive performance can also be affected, including reduced conception and litter size. New extraction methodologies are being developed to reduce the amount of gossypol in cottonseed meal.
棉籽粕多年来一直被用作动物饲料中的蛋白质补充剂。由于棉籽粕中存在一种多酚色素——棉酚，其在猪饲料中的使用受到了限制。单胃动物对棉酚的耐受性取决于年龄和物种，年龄较大的动物比年幼动物更不敏感。猪对棉酚中毒高度敏感，通常在食用一个或多个月后出现症状。日粮中添加铁盐似乎有解毒作用，在含棉酚的日粮中补充赖氨酸似乎能提高增重。繁殖性能也会受到影响，包括受孕率降低和产仔数减少。目前正在开发新的提取方法以减少棉籽粕中的棉酚含量。
