摘要
2008年3月29日～5月26日,在佳木斯市某东北林蛙养殖场,采用2组饲料饲喂东北林蛙蝌蚪,蝌蚪分为A组和B组。结果表明:饲喂T_1组饲料的蝌蚪41期和46期时的体重、体长和尾长明显大于饲喂T_2组饲料的蝌蚪;各组蝌蚪的成活率均在95%以上,各组蝌蚪完成变态的时间差异不显著;T_2组饲料的利用率要低于T_1组。
Tadpoles of Rana dybowskii in a frog farm in Jiamusi City were divided into 2 experimental groups,fed with two different diets：T_1 and T_2,from March 29 to May 26,2008.Results demonstrated the different utilization ratios of diets in these two groups： the body weight of the group fed with diet T_1 was heavier and body length longer than that fed with diet T_2 in 41 and 46 tadpole periods; the time of metamorphism did not different significantly between two groups;survival rate was all above 95%,so feed utilization ratio was higher in T_1 than in T_2.
