摘  要：
[目的]研究日本医蛭的生长性能及生长发育规律。[方法]对人工繁育的日本医蛭摄食习性及生长性能进行了分析,并利用Logistic、Gompetz、Von Bertallanffy 3种非线性生长模型对日本医蛭体重生长情况进行曲线拟合。[结果]日本医蛭的特定生长率随生长时间的延长而逐渐下降,幼蛭孵化后4 d喂食,生长率达到最高(10.99%/d),日本医蛭的体重随着投喂次数、日龄、摄食量的增加呈现上升趋势。3种生长曲线模型均能较好地拟合日本医蛭的生长曲线,其中以Gompertz曲线的拟合度最好(R2=0.999)。[结论]曲线模型对日本医蛭生长曲线的拟合和分析是可行的。通过生长曲线的拟合分析可及时掌握日本医蛭的生长发育规律,发现饲养管理中存在的问题。

摘  要：
[Objective] To study the growth performance and growth laws of Hirudo nipponia.[Method] The feeding habit and growth performance of H. nipponia in artificial breeding were analyzed. And the growth situations of H. nipponia were fitted and analyzed by using three nonlinear regression models( Logistic,Gompertz and Von Bertalanffy).[Result]The specific growth rate of H. nipponia gradually declined with the increase of time,the highest specific growth rate reached 10. 99%/d when H. nipponia larvae were fed after hatching 4 d. The body weight of H. nipponia increased with the feeding number,day-age and feeding amount. Three growth curve models all could fit the growth curve of H. nipponia better,and the fitting degree of Gompertz curve model was the best( R2= 0. 999). [Conclusion]The curve models were feasible for fitting the growth curve of H. nipponia. The growth laws of H. nipponia could be grasped timely by fitting the growth curves.
