摘　　要： 以省内5家反季节生产鹅场为对象,研究鹅的产蛋数、受精率、活胚率与洗浴池总细菌密度、大肠杆菌密度间的关系。结果表明,水体总细菌密度高的鹅场,其水体大肠杆菌密度也较高,两者成正相关,且种蛋受精率和活胚率偏低;水体总细菌密度低的鹅场,水体大肠杆菌密度也低,且种蛋受精率和活胚率较高。种鹅场洗浴池中细菌密度会对鹅种蛋受精率和活胚率产生影响,而对产蛋数无明显影响。 This experiment studied the correlations between laying, fertilizatioin rate, live embryo rate and total bacterials density, E.eoli density of bathing pool in 5 goose farms from guangdong province. Those results showed that E.coli density of goose farms with high density of total bacteria was high, and there was a positive correlation between the two densities; and the fertilization rate and live embryo rate of those goose farms were low. On the contrary, the fertilization rate and live embryo rate of goose farms were high, while total bacteria density and E.coli density were low. The above results indicated that total bacteria density and E.coli density of bathing pool would adversely affect the fertilizatioin rate and live embryo rate, but had no significant effet on laying in goose farm.
