摘  要:
以鱼粉和豆粕为蛋白源、大豆油为脂质源配制成3个蛋白质水平(35%、40%和45%)×2个能量水平(1.5×104J/g和1.6×104J/g)的6种试验饲料,投喂平均体重为(4.7±0.6)g的黄颡鱼,进行蛋白质和能量需要量的研究。经62 d饲养表明:黄颡鱼幼鱼配合饲料中的适宜蛋白质含量为41.47%~43.38%,最佳能量蛋白比为40.17。在6组试验饲料中,当蛋白质含量为40.38%,能量为1.622×104J/g时,体重增长率,蛋白质效率,肥满度均为最大值,分别为132.93%、1.14和1.76,饲料系数最低为2.17。

摘  要:
The optimum protein requirement and energy/protein ratio for yellow catfish Pelteobagrus fulvidraco juveniles(body weight,4.7±0.6 g) were determined using practical diets in a 3×2 factorial experiments.The experimental fish were reared for 2 month.Three protein levels(35%,40% and 45%) and two energy levels(1.5×10~4 J/g and(1.6)×10~4 J/g) were tested.Results were analysed based on ratio of weight gain,feed conversion ratio,protein efficient rate and condition factor.Results show the fitting requirement of protein is 41.47%~43.38%,optiomal energy/protein ratio is 40.17.When the content of protein test is 40.38% and energy is 1.622×10~4 J/g,the maximum weight gain(132.93%),protein efficiency ratio(1.14) and condition factor(1.76) and the lowest feed conversion ratio((2.17)) were obtained.
