Ten healthy weaning piglets of Landrace x Yorkshire (LY) in good body condition with body weight of (24 ± 1.27) kg were selected, and ten weaning piglets of Berkshire × LY (BLY) and Duroc × LY (...Ten healthy weaning piglets of Landrace x Yorkshire (LY) in good body condition with body weight of (24 ± 1.27) kg were selected, and ten weaning piglets of Berkshire × LY (BLY) and Duroc × LY (DLY) with similar situation were also selected respectively to study the growth performance of different cross combinations. Three groups of experimental pigs were bred with conventional diet. The results showed that the average dry matter intakes of combinations of BLY and DLY were slightly decreased by 4.97% and 5.47% compared with the combination of LY, while average daily gain was significantly increased by 3.13% and 1.14%, and feed-weight ratio was decreased by 7.94% and 6.35%, respectively; economic benefit per pig was increased by 0.61 and 0.41 yuan, respectively. The combinations of BLY and DLY have better growth performance, which can be promoted in the production.展开更多
