Effect of single or combined homo- and heterofermentative silage additives on the quality, nutritive value, and in vitro digestibility of ensiled wheat harvested at early dough stage of maturity

Abstract

The present study was conducted to evaluate the effect of single or combined homo- and heterofermentative silage additives on silage quality, nutritional composition, feed value, and in vitro digestibility of ensiled wheat harvested at early dough stage of maturity. The study was carried out as a completely randomized design with a 2 × 2 factorial arrangement of two levels of homofermentative silage inoculant (0 or 0.8 mg/kg) and two levels of heterofermentative silage inoculant (0 or 500 mg/kg) consisting of 4 groups with 4 replicates in each group. Control group received no silage additive. Remaining groups received either HMF, HTF, or a combination of both silage additives (HMF + HTF). pH and Flieg point of silage prepared with HMF and HTF alone or in combination were respectively lower and greater compared to control group. Nutritional composition, feed value, and in vitro true dry matter and organic matter digestibilities were unaffected among the treatments. In conclusion, the study shows that the application of single or combined HMF and HTF inoculants yields well-preserved wheat silage whereas the nutritional composition and in vitro digestibility may remain unaffected.
