ABSTRACT: The
object of this study was to determine the effect of cellulase and lactic acid
bacteria (LAB) on fermentation quality and chemical composition of wheat straw
silage. Silages were prepared using a small-scale fermentation system and the
moisture level was adjusted to 60% of fresh matter (FM) with deionized water.
Treatments were designed as: control silage without additives, LAB inoculant Lactobacillus casei Z3-1 (1.0 × 106 cfu·g-1 of FM), commercial inoculant L. plantarum FG 1 (1.0 × 106 cfu·g-1 of FM),
Z3-1 + cellulase and FG 1 + cellulase. The neutral detergent fiber (NDF), acid
detergent fiber (ADF) and crude protein (CP) contents of the wheat straw prior
to ensiling were 76.93%, 48.52% and 4.63% of dry matter (DM), respectively.
After 30 days of fermentation, the silages treated with LAB and LAB + cellulase
had a lower (P P P
