The aim of this study was investigated the possibilities of ensiling high moisture sugar beet pulp with using pith (by product of sugar cane), wheat straw, molasses and inoculants. High moisture sugar beet pulp (averagely 85 and 90% moisture) was mixed with different levels of pith (0, 5 and 10%), wheat straw (0 and 5%), molasses (0 and 5%) and a bacterial inoculants (contains lactobacillus plantarum) in order to decrease the effluent output, provide WSC and quickly pH reduction. The mixed materials were stored in experimental silos of 3.5 kg for three months. At the end of the incubation period, the experimental silos were opened and the silages were evaluated by measuring the fermentation and nutritional characteristics. The results indicated that using of sugar beet pulp with 85% moisture increased the amounts of dry matter, pH, ADF, dry matter digestibility and decreased the amounts of effluent, lactic acid and VFA production relative to 90% moisture (P 0.05). using of molasses decreased amounts of NDF, ADF, lactic acid and VFA but increased dry matter and dry matter digestibility significantly (P 0.05). Pith adding was caused reduction in the percentage of crude protein, ammonia N (dry matter basis), dry matter digestibility, WSC, effluent amounts, lactic acid, VFA and increased pH, dry matter, NDF and ADF (P 0.05). Wheat straw caused an increase the percentage of dry matter and decrease effluent amounts (P 0.05). Ammonia N (dry matter basis), pH, acetic and butyric acids contents decreased (in such treatments) and WSC and lactic acid increased (in such treatments) due to the added inoculants. Finally, it is possible to obtain high quality sugar beet pulp silage by increasing its dry matter content with pith, wheat straw, sugar beet molasses and adding inoculants.
