| 选取10头长X大、10头巴X长大、10头杜X长大健康无病、体况良好、体重相近的断奶仔猪，分为3组，研究不同杂交组合间的生长性能，3组试验猪全部饲喂常规日粮。结果显示，与长伊大组相比，巴伊长大、杜伊长大组猪平均干物质采食量稍降低4.97%、5.47%，平均日增重显著提高3.13%、1.14%，料重比下降7.94%、6.35%，头均经济效益增加0.61、0.41元。巴伊长大和杜伊长大组的生产性能较好，值得在生产中推广。 |

| It was selected 10 Landrace X Yorkshire, 10 Berkshire X LY, 10 Duroc X LY, healthy disease-free and in good body condition,similar body weight weaning piglets, divided into three groups, which was conducted to research on growth performance of different cross combinations. All three groups of piglets fed conventional diets. The results showed that compared with the combinations of LY, the combinations of BLY and DLY had 4.97% and 5.47% lower average dry matter intake and 3.13% (P<0.05) and 1.14% (P<0.05) higher average daily gain, respectively. The ratio of feed to gain was 7.94% and 6.35% lower for the combinations of BLY and DLY relative to LY. There was 0.61 and 0.41 yuan more economical profit for the combinations of BLY and DLY over LY. These results indicated that the combinations of BLY and DLY were more beneficial for the growth performance, which suggested to be applied in the practice. |
