对虾配合饲料研制中的主要问题之一是蛋白源不足。解决的途径除开拓新蛋白源外,充分利用现有蛋白源,是有现实意义的。我国年产棉籽饼300万吨以上,用作动物饲料的仅占16%。棉籽饼含粗蛋白质30～35%,棉仁饼含粗蛋白质约高5～10%。由于棉籽饼含游离棉酚和类环丙烯脂肪酸等有毒物质,可使畜禽慢性积累中毒,故多限量使用。近来有人研究棉籽饼脱毒的方法,以便扩大其饲用途径。棉籽饼在渔用饲料方面的应用与效果报道甚少。本文探索用棉籽饼作为对虾配饵主蛋白源养虾的效果和棉酚在虾体内的残留情况。
One of the main problems in the development of shrimp feed is insufficient protein source. In addition to exploring new ways to solve the protein source, the full use of existing protein sources, it is of practical significance. China’s annual output of cottonseed cake more than 3 million tons, only 16% for animal feed. Cottonseed cake containing crude protein 30 ~ 35%, cotton cake containing crude protein about 5 to 10%. Cottonseed cake contains free gossypol and cyclopropene fatty acids and other toxic substances, can make chronic accumulation of livestock poisoning, it is more limited use. Recently, some people have studied the method of detoxifying cottonseed cake in order to expand its feeding route. The application and effect of cottonseed cake in fishing feed have been reported very little. This paper explores the effect of using cottonseed cake as shrimp main protein source of shrimp feed and gossypol residues in shrimp.
