Effect of bacterial inoculant on pH and bromatological composition of sorghum silage (Sorghum bicolor L. Moench

Abstract

The objective of this work was to study the effect of three doses of commercial bacterial inoculant Sil-All (Alltech®), on the pH and the quality of the silage of sorgo, variety AG 2005. Sixteen experimental silos had been used, with capacity for 20kg of silage. The tested treatments had been T1 without the inoculante addition, T2: 2,5g/L of inoculante, T3: 5,0 g/L of inoculante and T4: 7,5 g/L of inoculante. After 60 days, the silos had been opened and samples removed for determination of pH, PB, FDN and FDA. The delineation was completely randomized, with four treatments and four repetitions. The different applied doses had resulted in significant difference (P < 0,05) for the MS content, being inferior for the treatment without inoculante (T1). The presence of inoculant in the silages had not significantly affected (P>0,05) values of pH, PB, FDN and FDA.
