摘要：

用3种不同蛋白含量(23.1%、37.6%和47.9%)的配合饲料投喂吉富品系尼罗罗非鱼幼鱼78d,结果显示,①随着饲料蛋白质含量从23.1%上升到47.9%,平均日增重从0.30g/d上升到0.74g/d,3组之间的日增重和体重有显著差异(P<0.05);饲料系数从1.53下降为0.98,3组之间的饲料系数有显著差异(P<0.05)。②不同的蛋白质水平对鱼体蛋白质和脂肪的含量有影响,各组之间差异显著(P<0.05),对灰分的影响差异不显著(P>0.05)。③蛋白含量为23.1%、37.6%和47.9%的配合饲料的成本分别为2.77元/kg、3.67元/kg、4.60元/kg。④初步认为蛋白含量为37.6%的配合饲料更适合吉富品系尼罗罗非鱼苗种培育的生产需要。

摘要：

Juveniles of GIFT strain oreochromis niloticus were maintained on diets of different dietary protein levels(23.1%, 37.6% and 47.9%)for 78 days within nine cages in a rectangle concrete tank. The results showed:①With dietary protein level vary from 23.1% to 47.9%, the average of the daily growth rate was increased from 0.30g/d to 0.74g/d. The average of the daily growth rate and final weight were both very significantly affected by experimental diets (P<0.05); Feed coefficient was decreased with dietary protein levels varying from 23.1% to 47.9%, feed efficient from 1.53 to 0.98.②Body composition analysis showed that the protein and fat of gross body of juvenile of GIFT strain oreochromis niloticus were affected by dietary protein content significantly(P<0.05), moisture insignificantly(P>0.05).③The cost of three diets was 2.77yuan/kg, 3.67yuan/kg, 4.60yuan/kg respectively.④The experimental result showed that the diet with 37.6% protein level was better than other diets.
