| 摘 要： | 对不同月龄的波德代杂种一、二代与土种羊的生产性能进行了比较,结果表明:3月龄、6月龄、周岁、成年等不同阶段的杂种二代羊在体重、体高、体长、胸围、管围等生长指标和土种羊相比均差异极显著(P<0.01);同时,除了3月龄杂种一代在体重、体高、体长方面与土种羊差异不显著外(P>0.05),在其余各阶段杂种一代与土种羊之间均表现出极显著差异(P<0.01)或显著差异(P<0.05),说明杂种优势明显。

| Abstract: | The growth indices of different period of Borderdale sheep’s crossbreds and Mongolian sheep were compared. The results showed that production of 3-month old, 6-month old, 12-month old and adult Borderdale sheep’s F2 were significantly different to Mongolian sheep in body weight, body height, body length, chest measurement and circumference of cannon bone (P<0.01). At the same time, Borderdale sheep’s F1 were significantly different to Mongolian sheep in body weight, body height and body leigth (P<0.05) at all stages except 3-month old stage. All these indicated the heterosis was obvious. |
