不同锌水平对生长期地鳖虫生长发育的影响

Effect of Diffetent Zinc Level on Eupolyphoga Sinensis Walker in Growth

为探索不同锌水平对地鳖虫生长发育的影响 ,选用 4～ 5龄中华真地鳖 2 4 0只 ,随机分成 4组 ,在基础日粮含锌 5 9.0 0 mg/ kg基础上 ,每组添加 Zn SO4 · 7H2 O分别使其含锌 10 0 m g/ kg、30 0 m g/ kg、5 0 0 mg/ kg。结果表明 ,在锌水平为 30 0 mg/ kg时生长期地鳖虫增重量和料重比最佳。

In order to explore the different zinc horizontal to Eupolyphoga Sinensis walkers growth, we select 4～5 ages 240 Eupolyphoga Sinensis walkers, divide 24 groups in random. In basic of consentrates contain 59 00 mg/kg zinc,each group increases ZnSO_4·7H_2O separately enable it to contain zinc 100 mg/kg, 300 mg/kg, 500 mg/kg. The result indicates, in the zinc level is when 300 mg/kg the vegetal period Eupolyphoga Sinensis walker insect increases the weight and the material anharmonic ratio is best.
