选用初始体重为 180～ 190g的正常健康鲤鱼 10 8尾 ,平均分成 3组 ,每组 36尾 ,每组设 3个重复。实验用 3种处理 ,即对照组 (基础饵料 )、基础饵料 +10× 10 - 4的鱼虾健、基础饵料 +2 0×10 - 4鱼虾健、(每公斤鱼虾健含 10 0g肉毒碱 ) ,在实验 6 0d后每个处理用 12尾鱼作运输试验 ,运输距离 50 0km ,运输时间近 14h。研究结果表明 :在基础饵料中添加鱼虾健可以显著地提高生长速度17 85%～ 2 2 53%和饵料利用率 (P <0 0 5) ,同时都对鲤鱼的耐长途运输能力没有影响。肉毒碱可以作为一种添加剂在鲤鱼饲料中使用
108 normal healthy carps with initial body weight of 180-190g were selected and divided into 3 groups with 36 mice in each group and 3 replicates in each group. The experiment used three kinds of treatment, namely, the control group (basal diet), basal diet +10 × 10 - 4 fish and shrimp, basal diet +2 × 10 - 4 fish and shrimp health, Alkali). After the experiment 60 days, 12 fish from each treatment were used for transportation test. The transport distance was 50 km and the transport time was nearly 14 hours. The results showed that the addition of fish and shrimp to the basic diet significantly increased the growth rate of 17 85% -2 22 53% and the utilization of food (P <0 05), while having no effect on long-distance transport ability of carp. Carnitine can be used as an additive in carp feed
