依据单因子梯度设计原理,采用进口鱼粉、豆粕为主要蛋白源制成蛋白质含量分别为50.2%、47.3%、44.3%和41.4%共4种试验饵料,研究不同蛋白质水平饵料对黄喉拟水龟生长的影响.结果表明,经过120 d对80只黄喉拟水龟幼龟的饲养,当饵料的蛋白质含量为47.3%时,黄喉拟水龟的生长速度最快,均显著高于其他3个组(P<0.05);蛋白质效率最高,极显著高于50.2%组(P<0.01),也分别显著高于44.3%组和41.4%组(P<0.05);耗料增重比最低,分别极显著低于44.3%组和50.2%组(P<0.01),也显著低于41.4%组(P<0.05).但不同蛋白质水平的饵料对黄喉拟水龟龟体蛋白质含量没有明显的影响(P>0.05).

Imported fishmeal and soybean meal were used as nitrogen sources of different protein levels to investigate the impact on growth on a total of 80 juvenile Mauremys mutica. Feedstuff was prepared with four protein contents of 50.2%, 47.3%, 44.3% and 41.4 % according to the principle of univariate factor gradient. After breeding for 120 days, the results showed that the growth rate of M. mutica fed with 47.3% protein content was markedly higher than those in the three other experimental groups, and differed significantly (P<0.05). The protein conversion rate was the most efficient and was significantly different from the 50.2% (P<0.01), 44.3%(P<0.05) and 41.4% (P<0.05) protein content groups; otherwise, the ratio of feed conversion and weight gain in the 47.3% protein content group was minimal, had very significant differences with the 44.3% and 50.2% protein content groups (P<0.01) as well as the 41.4% protein content group (P<0.05). However, protein content had no significant difference among M. mutica fed with feedstuff at different protein levels.
