鲤鱼饲料中喹烯酮最适添加量试验

Effect of Quinocetone on Body Composition of Carp

采用单因素梯度设计,以不添加任何促生长剂的饲料作对照,在等氮(蛋白质含量为32.67%)、等能量(12.89MJ/kg)的试验饲料中分别添加喹烯酮0mg/kg、25mg/kg、50mg/kg、75mg/kg、100mg/kg、125mg/kg饲养鲤鱼50d后,测定鱼体蛋白质等营养成分。结果表明:在鲤鱼饲料中添加适量的喹烯酮,可以有效的改善鲤鱼肌肉营养成分的含量。

Using single-factor gradient design, experimental feedstuff of equal nitrogen and equal energy were added Quinocetone by 0 mg/kg,25 mg/kg,50mg/kg,75 mg/kg, 100mg/kg and 125 mg/kg to feed carp for 50d,feedstuff added no growth-promoting agent being for comparision. Results showed that,content of protein and calcium in carp reached the highest when added Quinocetone by 50mg/kg,5.52% and 1.11% higher than control group. When Quinocetone was added by 75 mg/kg,contents of moisture,ash and lipid being the lowest,5.41%,1.76% and 0.75% lower than control group. When Quinocetone content in feedstuff ranged 50-75 mg/kg,nutrition composition of carp performs well.
