AbstractThis research was carried out to determine the effect of a homofermentative lactic acid bacterial (LAB) inoculant and formic acid-based preservative (FAP) on the aerobic stability and feed value of low dry matter (DM) small bale maize (Zea mays L.) silage. Maize was harvested at milk stage (26.4 % DM) and chopped about 2.0 cm. Commercial products Pioneer 1132 H/M F and KemiSile 2000 were used as LAB inoculant and FAP in this research. Additives were applied to maize LAB 106 cfu/g; FAP 3, 4 and 5 g/kg; LAB+FAP 106 cfu/g+3 g/kg, 106 cfu/g+4 g/kg, 106 cfu/g+5 g/kg, respectively. Control and additives applied maize ensiled in 30 kg capacity plastic bag as 3 replicates for each treatment. Silages were sampled for chemical and microbiological analyses on day 60 after ensiling and subjected to aerobic stability test for 5 days. In addition in vitro organic matter (OM) digestibility‘s and metabolic energy (ME) values of silages were determined. As a result, the homofermentative LAB inoculant, FAP and combination of LAB+FAP did not affect aerobic stabilities and decreased in vitro OM digestibility‘s and ME values of low DM maize silages.
