Abstract

This study was carried out to determine the effects of lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants as silage additives, on the fermentation, aerobic stability, cell wall content, and in situ rumen degradability of maize (Zea mays) silage. H/M F Inoculant No. 9927 (Medipharm, USA), and Sil-All (Alltech, UK) were used as lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants. Inoculants were applied to 106cfu g-1 silage levels. Maize was harvested at dent stages of maturity and ensiled in 1.5 liter special jars equipped with a lid that enabled gas release only. The jars were stored at 25±2°C under laboratory conditions. Three jars from each group were sampled for chemical and microbiological analyses on days 2, 4, 8, 15, and 50 after ensiling. All jars were opened at the end of the ensiling period (50 days) and subjected to an aerobic stability test for 5 days. In addition, rumen degradabilities of these silages were determined. Both inoculants increased characteristics of fermentation and in situ rumen dry and organic matter degradabilities but impaired aerobic stability of maize silages. Lactic acid bacteria+enzyme mixture inoculant decreased neutral and acid detergent fiber content and increased in situ rumen degradabilities of silages.
