| Abstract: | 40 heads of Chinese Holstein cattle were randomly divided into two groups, which were fed with sweet sorghum silage or corn silage and supplemented with same concentrate for 80 days, respectively. Results showed that mean milk yield per cattle of the group fed with sweet sorghum silage is higher that of the group fed with corn silage for 5.25 kg, which was increased by 12.16 percent. Mean concentrate intake per cattle of the group fed with sweet sorghum silage is lower that of the group fed with corn silage for 2 kg (\%P\%<0.01). Mean economic profit per cattle of the group fed with sweet sorghum silage is higher that of the group fed with corn silage for $4.54. |
