中文摘要:
      本文对黄喉拟水龟、三线闭壳龟、鳄龟周年生长进行了研究与比较.在广州自然温度下,人工饲养黄喉拟水龟343d,平均体重由10.3g增到71.9g,生长率为4.37mg·g-·d-;三线闭壳龟343d,由15.6g增到68.2g,生长率为3.68mg·g-·d-;鳄龟363d,由m.8g增到263.1g,生长率为5.08mg·g-·d-1.即在生长速度上,鳄龟>黄喉拟水龟>三线闭壳龟.在周年生长中,三种龟体重、背甲长、背甲宽与日龄;背甲长与宽;背甲长、宽与体重;均有着显著的正相关关系.温度与龟的生长有密切关系,低温抑制龟的生长,其影响程度依次为黄喉拟水龟>三线闭壳龟>鳄龟.同等条件下,三种龟个体间生长有差异,差异大小为鳄龟>黄喉拟水龟>三线闭壳龟.饵料转化效果,鳄龟>黄喉拟水龟>三线闭壳龟.日粮需求,三线闭壳龟>黄喉拟水龟>鳄龟.
英文摘要:
      The growth of Mauremys mutica , Cuora trifasciata and Chlydre serpentina in one year is studied and compared. Under the condition of natural temperature and artificial feeding in Guangzhou , when Mauremys mutica was reared for 343 days , its average weight increased from 10. 3g to 71. 9g and its growth rate was 4. 37mg·g-1 ·d-1, Cuora trif asciata for 343 days , from 15. 9g to 67. 8g , its growth rate 3. 68mg ·g-1 ·d-1; Chlydre serpentina for 362 days , from 10. 8g to 263. 1g , its growth rate 5. 09 mg·g-1·d -1. Namely , the growth rate , Chlydre serpentina’s > Mauremys mutica’s > Cuora trif asciata’s was found. The relationship among mass , carapace length , carapace width and day old are very significant . The growth rate of turtles decreased in low temperature and the result was Mauremys mutica’s > Cuora trif asciata’s > Chlydre serpentina’s. Under the condition of same feeding, the individual growth rate was different. That was Chlydre serpentina ’s > Mauremys mutica’s > Cuora trif asciata ’s. The effects of feed translating were Chlydre serpentina ’s > Mauremys mutica’s > Cuora trifasciata ’s. The quantity of ration was Cuora trif asciata ’s > Mauremys mutica’s > Chlydre serpentina’s.
