| Abstract: | The reproductive performance of Qinghai Bamei swine and the its crossbred with landrace swine and large Yorkshire swine at different parturition times were studied.The results showed that the reproductive performance indexes, such as the litter size,live litter size ,birth weight ,birth litter weight, weaning litter size, weaning weight,litter weight at weaning, were higher for Qinghai Bamei swine at third to sixth parturition times and the hybrids of Landrace with Qinghai Bamei Swine. The seven reproductive performance indexes of the hybrids of Large Yorkshire with Qinghai Bamei Swine were higher at fourth to sixth parturition times. |
