Fermentation Quality

Objective: To measure whether a microbial additive could effectively improve the fermentation quality of delayed-sealing (DS) silage, we studied the effects of inoculants of lactic acid bacteria (LAB) and cellulase enzyme on microbial populations, ensiling characteristics, and spoilage loss of DS silage of Napier grass in Africa.Methods: Quick-sealing (QS) and DS silages were prepared with and without LAB (Lactobacillus plantarum) inoculant, cellulase enzymes, and their combination. The QS material was directly chopped and packed into a bunker silo. The DS material was packed into the silo with a delay of 24 h from harvest.Results: In the QS silage, LAB was dominant in the microbial population and produced large amounts of lactic acid. When the silage was treated with LAB and cellulase, the fermentation quality was improved. In the DS silage, aerobic bacteria and yeasts were the dominant microbes and all the silages were of poor quality. The yeast and mold counts in the DS silage were high, and they increased rapidly during aerobic exposure. As a result, the DS silages spoiled faster than the QS silages upon aerobic exposure.Conclusion: DS results in poor silage fermentation and aerobic deterioration. The microbial additive improved QS silage fermentation but was not effective for DS silage.

Additive Control

This experiment was conducted to determine the ensiling characteristics and microbial changes of fodder ramie silage treated without additive (Control), or with molasses (M), lactic acid bacteria (LAB), and mixtures of lactic acid bacteria and molasses (LABM). Triplicate samples were randomly opened on days 0, 3, 7, 14, 28 and 60 of ensiling for sampling and the contents were processed for quality assessment and laboratory analysis. Compared with control silage, addition of M and LABM decreased pH and butyric acid while increasing lactic acid during ensiling (P < 0.05). For the LAB treatment, the pH value declined slowly at initial days then kept relatively stable at about 5.39 and the concentration of lactic acid increased for the first 7 days then maintained stable until day 60. The control silage showed a rise in pH and a significant decline in lactic acid concentration at later stage. Microbial changes had similar trend during ensiling for all the treatments where the lactic acid bacteria increased at initial days then showed a decline at later stage. Furthermore, LAB treatment had the highest (P<0.05) lactic acid bacteria population at almost all ensiling periods. It was concluded that both M and LABM treatment can improve the fermentation quality of fodder ramie silage to some extent, but the effects of adding lactic acid bacteria still need further research.
