It was evaluated the feed intake, the dry matter (DM) and nutrients total digestibility, ruminal characteristics and microbial efficiency in buffaloes fed with diet based on forage (70% of Cynodon spp hay and 30% of concentrate) with the addition of propolis based products (LLOS) in three concentrations (LLOSB3+, LLOSC1, LLOSC1+). Four crossbred buffaloes (Murrah ½ x ½ Jafarabadi), castrated, with 519.0 ± 13.0 kg were used in a 4x4 latin square with four treatments (Control, LLOSB3+, LLOSC1, LLOSC1+) and four periods. The diet was formulated to contain 60% of TDN and 11% of CP. The DM intake did not differ between the experimental diets. The addition of the LLOSC1 product increased (P <0.05) the coefficient of digestibility (CD) of DM (62,7% vs 67,2%), OM, NDF (56,6% vs 61,7%), CHT and TDN (62,8% vs 66,1%) . There was a tendency (P ? 0,10) for a higher CD of ADF (49,6% vs 56,5%), between the LLOSB3+ and the control diet. It was observed a significant effect of time and treatments (P <0.05) on ruminal pH, and the lowest pH (6.65) was obtained for LLOSC1 treatment. The LLOSC1 product provided higher production (P <0.05) of total VFA (141.89 vs 129.15) and trended (P ? 0.10) to a higher production of acetate (97.73 vs. 88.21 mM / mL) compared to the control. The ruminal dynamic variables and the efficiency of microbial synthesis (average of 9.85 g CPmic/100 g TDN) did not differ (P> 0.05) between treatments. Therefore, it is concluded that the product LLOSC1 may be indicated to improve the efficiency of diets based on forage for buffaloes.
