Effects of Different Doses of Lactobacillus brevis Addition to Oat (Avena sativa L.) Silage on Physical and Chemical Properties, Aerobic Stability, in Vitro Organic Matter Digestibility and Energy Value of Silage

This study aimed to determine the effects of the addition of different doses of Lactobacillus brevis to oat silage on the physical and chemical properties, aerobic stability, in vitro organic matter digestibility, and energy value of the silage. In the study, the treatment groups were oat control (OC), 1x106 (Lb6), 1x108 (Lb8) and 1x109 cfu/kg dry matter (Lb9) L. brevis inoculated oats. Inoculation of L. brevis into oat silage increased the number of lactic acid bacteria and decreased the pH of the silage at the time of opening. This inoculation decreased the organic matter, acid detergent fiber and neutral detergent fiber contents of the silages at opening compared to those of OC, while increasing the dry matter and crude protein contents. The L. brevis inoculation into oat silage decreased the pH values and yeast counts on the fifth day after opening the silages compared to OC, without affecting the amount of CO2 production and mold count. The inoculation did not affect the in vitro organic matter digestibility and metabolizable energy value of silage; but increased the net energy lactation value compared to OC. When the L. brevis doses are evaluated independently, it can be said that 1*108 and 1*109 cfu/kg DM doses contributed more effectively to oat silage, so any of these doses can be preferred.
