摘　　要：为研究非苜蓿日粮对泌乳奶牛生产性能及生产成本的影响,选用体况良好、产奶量及泌乳天数接近的泌乳奶牛40头,随机分成2组,对照组饲喂苜蓿日粮、试验组饲喂非苜蓿日粮,自由采食,自由饮水,试验期为6个月。结果表明:不同日粮对泌乳奶牛的生产性能没有显著影响(P>0.05),但试验组日粮可降低乳中尿素氮含量;非苜蓿日粮可以降低奶牛的饲养成本,每产1 kg奶降低0.08元;对于产奶量在8.5 t左右的奶牛,可以不使用苜蓿或者少使用苜蓿。In order to study the effects of non - alfalfa diets on production performance and production cost in dairy cows, 40 healthy cows with milk were selected and randomly assianed to two groups with twenty heads per groups. The control group was fed alfalfa di et, the experiment group was fed non-alfalfa diet, feed and water were provided ad libitum, the experiment lasted for 6 months. The results showed that, the milk performance, milk fat, milk protein, SCC, MUN of dairy cows were no significantly affected by different diets (!>0.05), but the urea nutrigon of experiment group was decreased. The cost per kilogram of milk was decreased by 0.08 yuan which was fed the non - alfalfa diet, but no significantly affect. Alfalfa can be avoided or less used by dairy cows with milk yield 8.5 t.
