| 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.

| 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 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 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. |
