| 摘 要： | 选用３６头晋南牛初生犊牛，分成试验１组、试验２组和对照组共３组，每组１２头（公母各半），试验组与对照组采用不同的断奶期和精料补饲量，以此来探讨早期断奶和早期补饲对增重的影响。结果表明缩短哺乳期，增加混合精料补饲量比延长哺乳期的效果好。哺乳期相同情况下，增加精料补饲量可取得较好的增重效果。

| Abstract: | Jinnan calves were selected and divided into three groups to investigate the influence of shortening lactation period and early supplementary feeding on body weight gain. The results indicated that shortening lactation period and early supplementary feeding with mixed concentrate had a better effect than lengthening lactation period on body weight gain. During a same lactation period, the quantity of mixed concentrate is the more the better for calves' body weight gain. |
