摘要
以广东省3家种鹅场(代号为A、B、C)为对象,检测了洗浴池和鹅血浆的内毒素水平,并比较和分析了各场种鹅的产蛋数、受精率和活胚率。结果显示:A场和B场洗浴池的内毒素水平无显著差异,均显著高于C场(P<0.05);A场的鹅血浆内毒素水平与B场无显著差异,显著高于C场,而B场与C场则无显著差异。此外,试验期间3家鹅场的鹅产蛋数相当;A场的鹅蛋受精率显著高于B场、但明显低于C场,C场则极显著高于B场(P<0.01);A场活胚率极显著低于B场,显著低于C场,B场则显著高于C场。表明洗浴池内毒素含量高的鹅场,其种鹅体内内毒素水平也相对较高,鹅蛋受精率和胚胎成活率偏低,影响种鹅生产水平。
In the experiment, path pool endotoxin concentration and plasma endotoxin level from three goose farms （named A,B,C, respectively）in guangdong province were detected, and the differences of laying rate, fertilization rate and live embryo rate were analyzed between three goose farms. The results showed that the endotoxin levels of farm A and B were all significantly higher than goose farm C （P〈0.05）, but there was no significant difference between the first two farms. The differences of plasma endotoxin levels between farm A and B, B and C, were not significant, but farm A significantly higher than farm C. There were no significant differencs in the number of laid eggs between three goose farms throughout experimental period. The fertilization rate of farm A was significantly higer than B, significantly lower than farm C, and the later was significant higher than farm B （P〈0.01）. The live embryo rate of farm A was significantly lower than farm B and C , and farm B was significantly higher than farm C . Those results therefore indicated that in the goose farm, path pool endotoxin concentration and plasma endotoxin level of which were higer, the fertilization rate and the live embryo rate were low, and therefore the reproductive performance of goose was adversely affected.
