Effect of bacterial additives, organic acid and urea on chemical composition, fermentation characteristics, gas production and digestibility parameters of triticale forage silage in vitro

A study was conducted to evaluate the effect of different additives on chemical composition, fermentation characteristic, gas production and digestibility parameters of triticale silage and its comparison with barley silage in a complete randomized design. Whole crop triticale and barley were harvested and chopped with a conventional forage harvester under farm condition to length of 2-3 cm. Representative of triticale and barley forage samples were packed manually, in triplicate into plastic bags. The filled silos were stored at ambient temperature and allowed to ensile for 3, 7, 21 and 45 days. The following treatments were applied to the forage samples: 1) triticale silage without any additives (control), 2) control bacterial inoculants, 3) control organic acid, 4) control urea and 5) barley silage. Results showed that triticale silages had higher DM content than barley silage, although there were no significant differences among triticale silages. However, barley silage had lowest pH than other treatment in all times after ensilage. Triticale silage treated with organic had highest aerobic stability (p
