试验表明,在鲤鱼、草鱼的饲料中,棉籽饼可达30％、尼罗非鲫的可达50％,前者若用0.5％的硫酸亚铁溶液去毒处理,其养鱼效果优于未去毒的,后者可直接饲喂。在上述用量范围内,未见试验鱼有毒性反应;鱼体营养成份和几项生理指标与对照鱼相当,鱼肉中游离棉酚的含量为0.0009～0.0017％,此值远低于0.02％的食品卫生标准。棉籽饼配合饲料用于生产性的池塘养鱼试验,亩净产成鱼300～625公斤,亩盈利700～1656元。 Tests showed that in the feed of carp and grass carp, the cottonseed cake can reach 30% and the nile carp can reach 50%. If the former is detoxified with 0.5% ferrous sulfate solution, its fish culture effect is better than that without Poisonous, the latter can be fed directly. In the above dosage range, no toxic reaction was observed in test fish. The nutrition composition and several physiological indexes of fish were similar to that of control fish. The content of free gossypol in fish meat was 0.0009 ~ 0.0017%, which was much lower than 0.02% of food health standard. Cottonseed cake feed for the production of fish pond test, mu net fish 300 ~ 625 kg, mu profit of 700 ~ 1656 yuan.
