以豆粕、菜籽粕、棉仁粕为主要蛋白源的配合饲料养青鱼(Mylopharyngodon piceus Richardson)和团头鲂(Megalabrama amlycephala Yih)鱼种,经两年试验,在群体增重率和饲料系数上都十分相似,而用棉仁粕为主要蛋白源的配合饲料饲养青鱼种,每生产1Kg鱼消耗的饲料蛋白明显低于豆粕和菜籽粕为主要蛋白源组,且饲养的鱼体质健壮,品味鲜美,经测定棉酚在鱼肉的含量明显低于国家标准,棉仁粕养鱼既安全又有效,而且价格低廉,完全可以和豆粕、菜籽粕相媲美,应该提倡和推广用棉粕为主要蛋白源在配合饲料中应用。
Mylopharyngodon piceus Richardson and Megalabrama amlycephala Yih were collected from soybean meal, rapeseed meal and cottonseed meal as main protein sources. After two years’ experiment, Are very similar, and cottonseed meal as the main source of feed mixed with herring species, each produced 1Kg fish consumption of protein was significantly lower than soybean meal and rapeseed meal as the main source group, and the fish body robust, taste Tasty, determined by gossypol in the fish content was significantly lower than the national standard, cottonseed meal is both safe and effective fish, and low prices, and soybean meal can be comparable to rapeseed meal, cottonseed meal should be promoted and promoted as the main The protein source is used in compound feed.
