摘要
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。
The results of study showed that, the proportion of cotton seed cake could account for 30% in the mixed feed of fish for Cyprinus carp and Ctenopharyngodon idellus, and could reach 50% for Tilapia nilotica. When the cotton seed cake in the former was detoxified with the solvent containing 0.5% of FeSO4 in advance,the efficiency on feeding fishes was better than that of the undetoxifiad.but the latter could be fed direct to fishes. Within the range of amount of the cotton seed cake mentioned above, no toxicity reaction was observed. The nutritional constituents and several physiological indexes in the fish meat were similar to that in the fishes under control. The content of free gossypol was 0.0009-0.0017%, much lower than 0.02% the critical value in the Chinese Standard of Food Hygine. When the mixed fish feed with the cotton seed cake were used in the productive experiments conducted in ponds, the net increase of yield of adult fish was 4500-9390 kg/ha., the net profit was RMB 15000-24840/ha.
