全混合日粮饲喂产奶牛经济效益试验

Study on Economic Benefit of Dairy Cattle Feeding with Total Mixed Ration

研究全混合日粮与非全混合日粮饲喂产奶牛,选择200头荷斯坦奶牛随机分为试验组和对照组,试验组饲喂全混合日粮,对照组饲喂相同配方和数量的草料,经30 d饲喂对比试验,结果表明:试验组日平均产奶量为23.52 kg,对照组日平均产奶量为21.78 kg,试验组比对照组日平均产奶量增加1.74 kg,日平均产奶量提高7.99%,差异极显著(P<0.01)。饲喂全混合日粮组比饲喂非全混合日粮组奶牛增收17 760元,经济效益明显。

The study aimed to evaluate the feeding effects of total mixed ration and none total mixed ration on dairy cattle.200 Holsteins cows were divided into experimental group and control group,total mixed ration was fed to experimental group and forage was fed to control group,after 30 days contrast test,the results indicated that average milk yield of experimental group was 23.52 kg,average milk yield of control group was 21.78 kg,milk of experimental group increased 1.74 kg compared to control group,daily milk yield increased 7.99%（P0.01）.Cows fed with total mixed ration group improved income $17 760 compared to cows fed with forage group,efficiency improved significantly.
