10%溴虫腈悬浮剂对野鸭繁殖性能的影响

Influence of 10% Chlorfenapyr SC on the Reproduction of Mallard Duck

摘要: 试验测定了10%溴虫腈悬浮剂对野鸭(Mallard duck)慢性繁殖的影响。溴虫腈试验浓度(有效成分)分别设计为0(对照)、0.5、1.0、2.0 mg/kg饲料。结果表明:溴虫腈对野鸭蛋产起始时间有一定影响,随着处理剂量的提高,初产蛋的时间略向后移;溴虫腈对野鸭蛋的蛋壳厚度、受精率及孵化率均没有影响;雏鸭14 d的成活率(以孵化出鸭数计),对照组、0.5 mg/kg饲料组、1.0 mg/kg饲料组、2.0 mg/kg饲料组分别为31.6%、29.2%、16.7%和17.0%。

Abstract: The effect of 10% chlorfenapyr SC on the reproduction of Mallard duck was tested. The test was composed of the control group, 0.5 mg/kg, 1.0 mg/kg and 2.0 mg/kg treated group. The results showed that the first date of laying egg was delay with the increase of treated concentration. There was no effect of chlorfenapyr on the eggshell thickness, fertility and hatchability. The results also showed that the 14-day old survivor rates of hatchlings in the control group, 0.5 mg/kg, 1.0 mg/kg and 2.0 mg/kg treated group were 31.6%, 29.2%, 16.7% and 17.0%, respectively.
