The effects of lactic aci̇d bacteria inoculants wi̇th enzymes on the fermentati̇on and aerobi̇c stabi̇li̇ty of tri̇ti̇cale si̇lages

This study was carried out to determine the effects of lactic acid bacteria inoculants with enzymes (LAB+E) on the fermentation characteristics, aerobic stability and in vitro organic matter digestibility of triticale silages. Triticale was harvested at milking and dough stage SILAID (Global Nutritech ®, TR), and MICROBIOS (Cuprem, USA) were used as homofermantative lactic acid bacteria+enzyme (HMLAB+E) and homofermantative+heterofermantative lactic acid bacteria+enzyme (HM+HTLAB+E) inoculants. Inoculants were applied to silages at 6.00 log10 cfu/g levels. After the treatment, whole crop triticale was ensiled in 1.0-L special polyethylene vacuum bags. The bags were stored at 20±2°C under the laboratory conditions. Three bags from each group were sampled for chemical and microbiological analyses 60th days after ensiling. At the end of the ensiling period, all silages were subjected to an aerobic stability test for 5 days. In addition, in vitro OMD of those silages were determined. The results showed that lactic acid bacteria and lactic acid bacteria+enzymes inoculants increased characteristics of fermentation and aerobic stability of triticale silages. Lactic acid bacteria+enzyme mixture inoculants decreased neutral detergent fiber, acid detergent fiber and celluloses content and increased in vitro organic matter digestibility of silages.
