摘要
本文报道了饲料蛋白质含量对翘嘴红鱼白生长的影响。试验分别用 5种不同蛋白质含量的饲料饲养平均体长 8厘米、平均体重 2克的 2龄翘嘴红鱼白30天 ,以观察饲料蛋白质含量对翘嘴红鱼白生长的影响。 5种试验饲料的蛋白质含量分别为 30 %、36 %、4 2 %、4 8%、5 4%。 (1— 5组 )试验结果表明 :饲料蛋白质含量在30 %— 5 4%的范围内 ,随着蛋白质含量的增加翘嘴红鱼白的生长比速、饲料效率都相应提高。第 4组较前 3组提高较多 ,而第 5组较第 4组变化不明显。蛋白质效率 1— 4组呈递增趋势 ,第 5组开始下降。因此 ,我们认为翘嘴红鱼白实用配合饲料的蛋白质含量在 4 8%~ 5
Effects of proteincontent (P.C)on the growth of Erythroculter ilishaefoumis are reported Five diets of different protein content(are respactively 30%,36%,42%,48%,54%)are used to feed 2 years old Erythroculter ilishaefoumis with 8 cm long and 2 g weight for 30 days ,to observe the effects of these diets on the growth Erythroculter ilishaefoumis. The results of 1-5groups showed that the acceleration rate and diet effciency rise as the P.C increasing within 30%-54% and the fourth group increases more than the third while the fifth is not so different with the fourth. protein efficiency increase from the first group to the fourth group and decrease from the fifth group therefore we consider that.P.C of practical diets of Erythroculter ilishaefoumis should keep in 48%-54%
