复合中草药对罗非鱼生长性能、免疫指标和体组成的影响

本试验采用单因素试验方法,研究复合中草药制剂对罗非鱼生长性能、免疫指标和体组成的影响。选用240尾罗非鱼苗,随机分为4个处理组,每个处理组3个重复,每个重复20尾。以基础饲料为对照组,试验组分别在基础料配方的基础上添加0.1%、0.2%、0.4%复合中草药制剂,饲养8周。结果表明:与对照组相比,0.1%和0.4%添加组增重率分别提高3.61%和4.09%,特定生长率均提高3.36%,饲料系数均降低4.5%(P<0.05);且适量中草药可降低转氨酶活性,提高罗非鱼粗蛋白质含量,降低粗脂肪含量。

Effects of Chinese herbal medicine on growth performance, immune indices and body composition in tilapia

This experiment was conducted to study Chinese herbal medicine on the growth performance,immune indices and body composition of tilapia by single factor test.Two hundred and fourty tilapia were selected and randomly assigned to 4 treatments with 3 replicates of 20 tilapia each.The cotrol group was fed basal diet,experimental groups were fed basal diet adding with 0.1%,0.2%,0.4% compound Chinese herbal medicine.After 8 weeks of feeding,the results showed that:Compared with the control group,growth rate of 1 % and 4 % groups increased by 3.61 % and 4.09 %,respectively,specific grouth rate both increased by 3.36 %,feed coversion ration both decreased by 4.5 %(P < 0.05).More over,appropriate amount of Chinese hebal medicine could decrease transaminase activity and crude fatty content,increase crude protein content.
