Results showed that there were no evident effects of different mechanical processes on the organic acid content(P＞0.05). The pH value of silages was all lower than 4.0 and the ratio of ammonia nitrogen to total nitrogen was all lower than 5.0, which improved the quality that all the silages in experiment were good. Though the effects of three different mechanical processes on the CP, CA and WSC contents of silages were evident, the silages were all excellent.
