在水温30℃条件下,摄食水平对幼鳖蛋白质表观消化率有显著影响(P<0.01);投喂频率对鲜鱼饲料组幼鳖表观消化率无显著影响(P>0.05),而对其蛋白质表观消化率的影响显著。在投喂配合饲料条件下,表观消化率和蛋白质表观消化率均在中间摄食水平(此时干物质的摄食率为0.97%)时达到最大,分别为76.26%和81.22%;在饱食状态下,其表观消化率和蛋白质表观消化率分别为72.36%和78.05%,日投喂2次鲜鱼组的幼鳖表观消化率和蛋白质表观消化率分别为92.05%和96.84%;投喂1次鲜鱼组的分别为92.17%和95.27%。 At the water temperature of 30 ℃, the dietary level had significant effects on the apparent digestibility of protein (P <0.01). The frequency of feeding had no significant effect on the apparent digestibility of juvenile soft-shelled turtle (P> 0.05) The apparent digestibility of protein was significantly affected. The apparent digestibility and apparent digestibility of protein reached the maximum at the intermediate feeding level (dry matter feed rate was 0.97% at this time), which were 76.26% and 81.22% respectively when fed with compound feed. , The apparent digestibility and apparent digestibility of protein were 72.36% and 78.05%, respectively. The apparent digestibility and protein digestibility of juvenile turtles fed 92% and 96.84% resp. ; Once-fed fresh fish were 92.17% and 95.27% respectively.
