研究以鱼粉为蛋白源,配制粗蛋白含量分别为6%、13%、20%、27%和34%的饲料,对90只平均体质量为3.79 g的刺参幼参平均分成5组进行投喂,研究饲料中不同的蛋白水平对仿刺参幼参生长、耗氧率和排氨率的影响。结果表明,粗蛋白含量为20%的饲料组,幼参特定生长率最高,与其他对照组存在显著差异(P<0.05);随饲料中蛋白水平的升高,幼参的耗氧率呈逐渐下降趋势,排氨率呈先下降后上升的趋势。 In this study, fish meal was used as a protein source to prepare 6%, 13%, 20%, 27% and 34% crude protein diet respectively, and 90 juvenile sea cucumbers with an average body weight of 3.79 g were evenly divided into 5 groups Effects of different dietary protein levels on the growth, oxygen consumption rate and ammonia excretion rate of the sea cucumber seedlings were studied. The results showed that the specific growth rate of juvenile ginseng was the highest with 20% crude protein content (P <0.05), and the oxygen consumption rate of juvenile ginseng gradually increased with the increase of dietary protein level Downtrend, ammonia excretion rate was the first to decline after rising trend.
