在饲料中添加0.2%、0.4%和0.8%的氧化三甲胺饲养罗非鱼,经过60d的生长试验,观察不同添加量的氧化三甲胺对罗非鱼的生长、机体营养成分组成的影响。养殖试验结果表明,添加氧化三甲胺可以促进罗非鱼生长,并对改变罗非鱼内脏的相对重量,提高肥满度有一定作用。尤其0.2%的试验组与对照组相比,末重、日增重和特定生长率均有显著的差异。此外,添加氧化三甲胺可以显著降低罗非鱼肌肉和肝胰脏中的粗脂肪含量。
Tilapia were fed with 0.2%, 0.4% and 0.8% trimethylamine oxide respectively. The growth of tilapia was observed after 60 days. The effects of different concentrations of trimethylamine oxide on the growth of tilapia and the composition of nutrients were observed. Breeding test results show that the addition of trimethylamine oxide can promote the growth of tilapia, and to change the relative weight of tilapia viscera, improve the degree of fullness play a role. In particular, 0.2% of the test group compared with the control group, the final weight, daily gain and specific growth rates were significantly different. In addition, the addition of trimethylamine oxide significantly reduced crude fat in tilapia muscle and hepatopancreas.
