| Abstract: | A total of twenty Holstein cows were randomly divided into two groups of ten animals each, the experiment group was added 2kg/t enzyme and 200g/t xylanase in the diet, control group was not added, each cow fed the same corn silage and rice straw. The results showed that the experiment group had not significant differences in feed intake and milk production compared with the control group,but feed costs for one-kilogram milk of the experiment group decreased by 0.3 Yuan. |
