To investigate the effect of feeding dairy cows diets containing lucerne hay, centrosema hay, and groundnut haulms (crop residue) on dry matter intake (DMI), milk yield, and milk composition, nine multiparous Friesian-Holstein cows in their mid-lactation stage were used in a 3 × 3 crossover design replicated three times. Dairy cows fed lucerne hay had significantly (p < 0.001) higher DMI than dairy cows fed centrosema hay. DMI for cows fed groundnut haulms and lucerne hay was not significantly different. Daily milk yield for dairy cows fed diet containing lucerne hay was significantly (p < 0.01) higher than that for dairy cows fed diets containing groundnut haulms or centrosema hay. Milk composition and body condition scores of the cows were not significantly affected by either lucerne hay, groundnut haulms, or centrosema hay. Overall, the results in this study indicated that feeding dairy cows diets containing lucerne hay increased milk yield.
为研究给泌乳中期的奶牛饲喂含苜蓿干草、距瓣豆干草和花生藤（作物残渣）的日粮对干物质采食量（DMI）、产奶量和乳成分的影响，采用3×3交叉设计，对9头经产弗里生-荷斯坦奶牛进行了3次重复试验。饲喂苜蓿干草的奶牛干物质采食量显著高于饲喂距瓣豆干草的奶牛（p<0.001）。饲喂花生藤和苜蓿干草的奶牛干物质采食量无显著差异。饲喂含苜蓿干草日粮的奶牛日产奶量显著高于饲喂含花生藤或距瓣豆干草日粮的奶牛（p<0.01）。苜蓿干草、花生藤或距瓣豆干草对奶牛的乳成分和体况评分均无显著影响。总体而言，本研究结果表明，给奶牛饲喂含苜蓿干草的日粮可提高产奶量。
