四川白鹅和豁眼鹅在武汉繁殖性能比较

从四川南溪县、山东莱阳市分别引进四川白鹅和豁眼鹅,在武汉地区进行饲养对比试验,分析两个不同品种在武汉地区气候条件下的繁殖性能.结果表明:四川白鹅,开产日龄263 d,产蛋持续期160 d,只均产蛋数64枚,均蛋重135.77 g,产蛋率40%,受精率86.0%,受精蛋孵化率85.8%;豁眼鹅,开产日龄298d,产蛋持续期118d,只均产蛋数38枚,均蛋重122.98g,产蛋率32%,受精率84.0%,受精蛋孵化率84.9%.二者受精蛋孵化率差异无统计学意义(P>0.05),其他指标差异有统计学意义(P<0.05).实验数据说明,在武汉地区气候条件下,四川白鹅的繁殖性能优于豁眼鹅.

Reproductive Performance Comparison of Sichuan White Geese and Huoyan Geese in Wuhan

Sichuan White Geese from Nanxi Sichuan and Huoyan Geese from Laiyang Shan-dong were bred in Wuhan,their reproduce performances were compared and analyzed.The results showed that Sichuan White Geese＇s first egg age was 263 days,the laying cycle was 160 days,the number of egg for each goose was 64,the average egg weight was 135.77 g,the average laying rate was 40.0%,the fertility rate was 86.0%,and the hatching rate of fertilized eggs was 85.8%;Huoyan Geese＇s first egg age was 298 days,the laying cycle was 118 days,the number of egg for each goose was 38,the average egg weight was 122.98 g,the average laying rate was 32.0%,the fertility rate was 84.0%,and the hatching rate of fertilized eggs was 84.9%.The hatching rate of the fertilized had no significant difference（P 0.05） and the others had significant difference（P 0.05）.The re-sults showed that the reprodutive performances of Sichuan White Geese were better than Huoyan Geese in Wuhan.
