台系杜洛克猪产仔数重复力的评定

Evaluation of repeatability of litter size at birth in Taiwan Duroc pig

为了解台系杜洛克母猪重复力遗传参数在国内的适应性,充实完善台系杜洛克猪产仔数的重复力,继续选育提高杜洛克猪育种水平及经济效益。通过采用组内相关的方法,对某大型种猪企业的台系杜洛克猪1~8胎次产仔数的重复力进行估测。结果表明：台系杜洛克猪1~8胎次的平均产仔数分别为8.6头、9.65头、9.35头、9.00头、8.30头、8.80头、7.65头;台系杜洛克猪8个胎次平均产仔数为8.44头;台系杜洛克猪产仔数的重复力为0.42。

In order to adaptive genetic parameter solution of Taiwan Duroc sows repeatability in domestic,to enrich and perfect repeatability litter size in Taiwan Duroc pig,continue to improve a well bred breeding,To improve the economic benefits of animal breeding. Methods by using the intraclass correlation,estimation of repeatability of Taiwan Duroc pigs from a large swine enterprises 1-8 parity litter size. The results were showed as follow： average litter size of Taiwan Duroc pigs 1-8 parity were 8.6;9.65;9.35;9;8.30; 8.80;7.65;respectively. Taiwan Duroc pig 8 parity average litter size was 8.44; repeatability Taiwan Duroc pig litter size was 0.42.
