摘要
分别在对虾配合饲料中添加酸败鱼油和含黄曲霉毒素花生饼粉养虾，鱼油的酸价为０２、８０、２２４、３１０ｍｇ／ｇ，黄曲霉毒素Ｂ１的含量为４７２０ｐｐｂ、７８７ｐｐｂ。试验进行了２８天，其结果如下：随着鱼油酸价的增高，以上四组对虾的增重率依次为７２４％、３７０％、２９２％、２７５％；成活率依次为８３１％、５９６％、５８０％、５３０％；消化率依次为７８７％、６８５％、６３３％、６０１％。喂含黄曲霉毒素饲４７２０ｐｐｂ和７８７ｐｐｂ的两组对虾的增重率仅为对照组的４３９％和４５４％；消化率为对照组的７９４％和８３２％，而且成活率也较低，其对虾体内未检出黄曲霉毒素。
The tested prawns were fed for 28 days with the compound feed in which acid value of fish oil varied from 0.2 to 8.0, 22.4, 31.0 mg/g and Aflatoxin contents were 472.0 ppb and 78.7 ppb respecitively. The results came our as follows: 1. As the acid value increased, the growth rates increased by 72.4%, 57.0%, 29.2%, 27.5%, the digestibility rates increased by 78.7%, 68.5%, 63.3%, 60.1% and the survival rates increased by 83.1%, 59.6%, 58.0%, 53.0%. 2.When the prawns were fed with the compound feed which Aflatoxin contents were 472.0 ppb and 78.7 ppb, the growth rates were only 45.4%, 43.9% of that of the control group, and digestibility rates were 79.4%, 83.2%. The survival rates were also relatively low.
