| 摘 要： | 中国荷斯坦奶牛60头饲喂4种不同紫花苜蓿干草配比、不同精粗比的日粮，以研究日粮配方对奶牛产奶量、乳脂率、经济收益的影响。试验结果说明，大比例紫花苜蓿干草日粮（紫花苜蓿占24％DM）乳脂率显著（P〈0．05）或极显著提高（P〈0．01）；日粮营养水平提高，产奶量提高（P〈0．05；P〈0．01）；最佳经济效益日粮为含大比例紫花苜蓿，营养水平较低的日粮（P〈0．01）；在大的精粗比例下，紫花苜蓿干草不是日粮成本的限制因素，而青贮饲料配比为日粮成本的限制因素。只有合理安排精粗比例，适当使用紫花苜蓿干草，可提高奶牛饲养经济效益。

| Abstract: | 60 China Holstein Cows were allocated to 4 rations which have different levels in lucerne hay and grain concentrate:roughage ratio,to examine the effect of formulas on milk yield,fat percentage and economic benefit.The trial results indicated:larger content of lucerne hay(24% DM),fat percentage was higher(P<0.05)or the highest(P<0.01);nutritional level was improved,milk yield was increased(P<0.05 or P<0.01);optimum economics ration was the one which has the highest level of lucerne hay and nutritional levels lower(P<0.01);silage content was limiting factor of ration cost but not lucerne hay at large ratio of concentrate:roughage;It is suitability of concentrate:roughage ratio and lucerne hay level that can increase economic benefit of dairy cows. |
