Effects of Adding Different Levels of Lactobacillus Inoculant to Alfalfa Silage Ensiled With Orange Pulp on In Vitro Gas Production and DM Digestibility

This study was conducted to study the effects of supplementation alfalfa silage with orange pulp and difference of Lactobacillus buchneri on in vitro dry matter digestibility and gas production. wilted alfalfa with no additive (control), wilted Alfalfa and orange pulp (1750 g wilted Alfalfa mixed with 750 g fresh orange pulp) treated with LAB for final application rates of 0, 2.5, 5 and 7.5 g LAB inoculant/ton of wilted alfalfa and orange pulp (LAB0, LAB1, LAB2, LAB3, respectively). Alfalfa hay harvested at flowering stage and after 24 hours wilted and mixed orange pomace with ratio of 2100 g and 760 g, respectively, and was ensiled for 90 days. The data were analyzed in a completely randomized design with three replications. After 24 h incubation, treatments AO (alfalfa + orange pulp) and CON (without additive) had the highest and lowest in vitro gas production (p<0.05) and adding orange pulp and molasses increased gas production. Adding inoculant decreased in vitro DM digestibility. Results showed that ensiling alfalfa with orange pulp and molasses can improved silage quality and increased gas production and in vitro DM digestibility.
