| 摘 要： | 根据泌乳奶牛产奶量的差异,在其精料中添加适量的过瘤胃脂肪,观察泌乳奶牛生产性能和体况所受的影响。试验结果表明,过瘤胃脂肪的添加使奶牛的产奶量显著增加,乳的成分发生变化,其中乳脂含量上升了6.23%,乳蛋白的含量下降了4.51%。同时,添加过瘤胃脂肪,显著地改善了泌乳牛的体况,对产量高而体质赢瘦及虚弱的奶牛具有重要意义。

| Abstract: | Test of feeding supplemental bypass fat on dairy cattle based on their different lactation period and milk pro-duction has been made.The effect for supplemental fat on body condition and milk production of dairy cattle has been observed.Result shows that supplemental fat can remarkably increase milk production.At the same time ,milk protein de-creases by4.51%,milk fat raises6.23%.It also shows that the dairy cows' body condition score have obviously enhanced after fed supplemental bypass fat. |
