Performance of breeding,growth,slaughter and meat quality of four hybrid pigs were studied with Jinhua pig and six white pig as female parent,Landrace and Berkshire pig as male parent. The results showed that the indexes of Landrace × Jinhua hybrid pigs,inculding number of born alive (12. 51),daily weight gain (510. 38 g·d~(-1)),feed to gain ratio (3. 52),lean meat rate (60. 27%),backfat thickness (27. 32 mm),skin thickness (3. 11 mm),armbling score (2. 85),average shearing force (15. 64 N),crude protein (260 mg·g~(-1)) were significantly superior to other hybrid combinations. Through performance measurement of four hybrid pigs,the Landrace × Jinhua hybrid pig was selected as the best commodity substitute,which provided scientific basis for its application in the farm.
