研究在饲料蛋白水平、能量水平均能满足生长需要的前提下,饲料中添加不同含量及不同品质的脂肪对团头鲂鱼种生长的影响。试验所用的精制饲料用进口酪蛋白及脂肪、糊精、维生素、矿物质、纤维素加工而成,脂肪为豆油与鳕鱼肝油。52d 饲养试验的结果表明,团头鲂鱼种饲料中脂肪的适宜含量为4%～6%(P<0.05);鱼油的饲养效果明显优于豆油;饲料中同时添加豆油和鱼油,鱼体生长情况较添加单一的等量豆油或鱼油为差。
The effects of adding different contents and different quality fats on the growth of bream fish were studied under the premise of the feed protein level and energy level can meet the growth needs. The refined feed used in the experiment is made of imported casein and fat, dextrin, vitamins, minerals and cellulose, and the fat is soybean oil and cod liver oil. The result of 52d feeding experiment showed that the suitable content of fat in bream fish was 4% -6% (P <0.05), the feeding effect of fish oil was better than that of soybean oil, while the soybean oil and fish oil were added to the feed, the growth of fish body The situation is worse than adding a single equal amount of soybean oil or fish oil.
