摘要
该文利用棉籽粕替代水产饲料中鱼粉,作为主要蛋白源,以降低养殖成本,改善水体生态环境。以蛋白质和磷的体外消化率为评价指标,对棉籽粕以及钙磷的添加量做了优化。结果表明,棉籽粕替代33.33%的鱼粉,磷需要量为0.8%,并添加2.0%石粉时,饲料的体外消化率达到最大值。
In this paper,to reduce farming costs and improve the ecological environment of the water,cottonseed meal instead of fish meal in aquaculture feed was used as the principal protein source.With in-vitro digestibility of protein and phosphorus as mainly evaluation indictor,the supplementation of cottonseed meal,calcium and phosphorus were optimized.The results showed that in-vitro digestibility of the feed reached the maximum while cottonseed meal instead of 33.33% fish meal,with 0.8% phosphorus required and 2.0% powder added.
