Abstract

In order to investigate the effects of mixing different organic acids and maize powder on the silage quality of high moisture banana stems and leaves and banana pseudostems, two types of silage materials-fresh banana stems and leaves and banana pseudostems (leaving for 48 hours, and the corresponding moisture content was 91.1% and 94.8%) were ensiled with different organic acids and maize powder. The banana stems and leaves were ensiled with 10% maize powder (YY group), 10% maize powder+0.6% formic acid (YJ group), 10% maize powder+0.4% acetic acid (YS group), 10% maize powder+0.5% calcium propionate (YB group), respectively, there was a control without organic acids and maize powder (CK1 group). The banana pseudostems were ensiled with 10% maize powder (JY group), 10% maize powder+0.6% formic acid (JJ group), 10% maize powder+0.4% acetic acid (JS group) and 10% maize powder+0.5% calcium propionate (JB group), respectively, and there was a control without organic acids and maize powder (CK2 group). Silages were opened after ensiling 45 days, and sensory evaluation and laboratory evaluation were performed for silages of each group. The results showed that the sensory evaluation of silages for banana stems and leaves and banana pseudostems after treatment with different additives was better than that of the corresponding control group (CK1 and CK2 groups). Compared with the corresponding control group, the addition of maize powder (YY and JY groups) significantly reduced the pH (P<0.05), significantly increased the lactic acid content (P<0.05), and significantly reduced the ammonia nitrogen content (P<0.05). The contents of dry matter, crude protein, neutral detergent fiber and acid detergent fiber in YJ, YS, YB and YY groups with different organic acids were not significantly different (P>0.05), while the contents of dry matter, neutral detergent fiber and total phenol in JY group were significantly lower than those in JJ group (P<0.05), and the group added with formic acid and maize powder was used in banana stems and leaves group (YJ group) and banana pseudostems group (JJ group) had the lowest lactic acid content and the highest soluble carbohydrate content. It can be seen that the addition of different organic acids and maize powder in silage can improve the silage quality of high moisture banana stems and leaves and banana pseudostems, with the best silage quality when adding formic acid and maize powder.
