青贮

The result showed that 70% initial moist was suitable for ensilage, and the water-soluble carbohydrate content was more than 40mg/g-DM, or would result in fail in ensilage because low sugar content could not support lactic acid bacteria to produce lactic acid for drop in pH rapidly.

The results of silage test show that in each cutting of all treatments, the silaging result of half-hay+BM+PFJ is best, the next is half-hay ferment, result of fresh grass straight fermenting is worst. In each cutting the content of CP between half-hay+BM+PFJ and the raw material grass has tiny difference (respective discrepancy from others 0.18%, 0.60% and 0.94%).

各种处理中，半干+BM+PFJ 组与原料草粗蛋白差异最小，三茬半干+BM+PFJ 处理CP 含量和原料草分别相差0.18%，0.60%，0.94%，该处理青贮料NH3-N 最低，NDF 含量与原料草差异小，pH 最低，评定得分最高，说明半干+BM+PFJ 青贮效果最好，半干草添加PFJ 和BM 后能能促进乳酸发酵，能有效地改善苜蓿青贮的发酵品质，提高青贮饲料质量。

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.

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.
