摘要
以酸贮玉米秸秆(添加复合有机酸)为试验组日粮粗饲料,以一般青贮玉米秸秆为对照组日粮粗饲料饲喂奶牛,探讨酸贮玉米秸秆的饲喂效果。结果表明:(1)试验组与对照组相比,产奶量平均提高7.35%,乳脂率平均提高0.76%。(2)试验组与对照组相比,每头牛每日平均多增加经济收入为1.29元。(3)用酸贮玉米秸秆饲喂奶牛,经济效益明显,整个试验期奶牛健康状况良好。
Sour ensiling corn stover is used in the experiment group and the general ensiling maize stover is used in the control group. The aim is to study the effect to feed cow using sour ensiling maize stover. The result showed: (1)The milk yield has been raised 7.35% and the milk fat percentage has been raised 0.76% in the test group than in the control group. (2)The economic income of per cow in the test group has raised 1.29yuan per day than in control group. (3) The economic efficiency is remarkable to feed cow using sour ensiling maize stover.
