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(紫花苜蓿为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。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。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 highest（P〈0.01）;nutritional level was improved, milk yield was increased （P〈0.05 or P〈0.01）;opfimum economics ration was the rote which has highest level of lucerne ha） 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.
