喹烯酮对鲤鱼肌体组成成分的影响

摘要：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：当喹烯酮添加量为50mg/kg时，鲤鱼肌体中的蛋白质和钙含量最高，与对照组相比，分别提高5.52%和1.11%；当喹烯酮添加量为75 mg/kg时，水分、灰分和脂肪含量达到最低，与对照组相比，分别下降了5.41%、1.76%和0.75%。

Effect of Quinocetone on Body Composition of Carp

Using single-factor gradient design,experimental feedstuff of equal nitrogen and equal energy were added Quinocetone by 0 mg/kg,25 mg/kg,50 mg/kg,75 mg/kg,100 mg/kg and 125 mg/kg to feed carp for 50 days,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 50 mg/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 lowe...
