| Abstract: | 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: (l)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. |
