摘要
通过对两个品系雁荡土鸡父母代的产蛋性能、蛋品质和孵化性能进行为期365 d的跟踪测定,并分析其繁殖能力,结果表明:Ⅰ系雁荡土鸡年产蛋量220枚,平均蛋重46.42 g,蛋形指数1.29,产蛋年平均产蛋率60.27%,受精率92.3%,受精蛋孵化率93.2%;Ⅱ系雁荡土鸡年产蛋量217枚,平均蛋重45.32 g,蛋形指数1.25,产蛋年平均产蛋率59.45%,受精率91.6%,受精蛋孵化率91.9%。两品系间繁殖性能差异不显著。与其他品种比对,雁荡土鸡产蛋性能显著低于专门化蛋鸡品种,但略高于灵昆鸡、仙居鸡等蛋肉兼用型同类品种,且蛋品质与孵化性能均处于较高水平。
The laying performance,hatching performance and egg quality of Yandang native chicken parental generation of two lines were measured in a 365 day experiment. The reproductive performance was also analyzed in this paper. The result was that,forⅠline,the annual egg yield was 220,the average egg weight was 46. 42 g,the egg shape index was 1. 29,the average egg laying rate in a laying year was 60. 27%,the egg fertilization rate was92. 3%,the hatching rate of fertilized egg was 93. 2%. For Ⅱ line,the annual egg yield was 217,the average egg weight was 45. 32 g,the egg shape index was 1. 25,the average egg laying rate in a laying year was 59. 45%,the egg fertilization rate was 91. 6%,the hatching rate of fertilized egg was 91. 9%. Reproductive performance difference between the two lines was not significant. Compared with other species,the laying performance of Yandang native chicken was significantly lower than that of specialized lines,but slightly higher than that of Lingkun chicken and Xianju chicken,which belong to the similar type of species. And the egg quality and hatching performance were all at a high level.
