摘　　要：目的:为探索在奶牛日粮中添加饲料甜菜对其泌乳量的影响,提高奶牛养殖的经济效益。方法:2011年9月20日至11月20日,选择健康黑白花奶牛6头,随机分为试验组(饲料甜菜组)和对照组(普通饲料组),进行饲料甜菜对奶牛产奶量的影响试验。结果:试验组比对照组头均日产奶量增加2 kg,产奶量提高7.9%,差异极显著(P<0.01);试验组比对照组粗饲料采食量增加14%,饲料成本增加504元,差异极显著(P<0.01);试验组比对照组头日均收入高6.8元,增加纯收入1 124元,经济效益提高13.2%,差异极显著(P<0.01)。结论:饲料甜菜饲喂奶牛,牛奶产量和质量明显提高,经济效益提高,在实践中应大力推广。Objective：To explore the effect of fodder beet on the yield of milk in dairy cattle and improve the economic benefit.Methods：Healthy Holstein dairy cattle were randomly divided into experimental group（feeding with fodder beet） and control group（feeding with common forage）,and the experiment duration was 2 months.Results：It showed that the daily yield of milk in the experimental group,which was increased by 7.9%,was 2 kilograms higher than that of the control group（P0.01）;The feed intake in the experimental group was increased by 14% with a cost increasing of 504 yuan compared with that of the control group（P0.01）;At the same time,the economic benefit from each cow in the experimental group was increased by 13.2% with an average daily income increasing of 6.8 yuan and net income increasing of 1 124 yuan compared with that of the control group（P0.01）.Conclusion：The fodder beet could effectively improve the output and quality of milk in dairy cattle,and increase the economic benefit of dairy cattle industry.
