摘要
采用4.5%高效氯氰菊酯乳油喷洒饲草,使4组家兔每日每千克体重染毒高效氯氰菊酯分别为0mg、1.5mg、3.0mg、4.5mg,持续56d后采用常规方法对精液品质进行检查。结果各剂量组家兔体重、睾丸重量、精液量及其pH等方面均无显著性差异(>0.05);与对照组相比,1.5mg/kg体重试验组的精子密度、精子活力、畸形率无明显变化(>0.05),但3.0mg/kg、4.5mg/kg剂量组则发生显著变化(<0.05)。表明当家兔高效氯氰菊酯染毒量达到3.0mg/kg体重时即可导致家兔精子密度、精子活力、畸形率等方面发生异常,对家兔具有一定的生殖毒性。
4.5% - CP emulsion were sprayed on forage which were fed to rabbits. The dose of -CP of the 4 groups were 0 mg, 1.5 mg, 3.0 mg, 4.5 mg every kilogram of body weight each day respectively. After the rabbits being treated for 56 days, their semen qualities were examined with routine methods. There was no significant difference in body weight, testicle weight, semen quantity and pH among the 4 groups ( > 0.05). Compared with control group, Sperm density , sperm motility and malformation rate in 1.5mg/kg group didn't change significantly, but changed markedly in 3.0 mg/kg groups and 4.5mg/kg groups( < 0.05),. These indicated that the ingestion of - CP in rabbits reach 3.0mg/kg weight could cause abnormality in rabbit sperm density ,sperm motility and malformation and toxicity on rabbit reproduction.
