| Abstract | This study was conducted by using an in vitrogas production technique to study the level of enzyme supplements. Dietary treatments were total mixed ration without (control) and with exogenous fibrolytic enzyme (EFE) supplementation at 250, 500 and 750 mg/kg DM, respectively. The in vitrodry matter digestibility (IVDMD), In vitroorganic matter digestibility (IVOMD), metabolizable energy (ME), ammonia nitrogen (NH3-N), total digestible nutrient (TDN), the partitioning factor of incubation (PF) and microbial crude protein (MCP)at 24 h. after incubation of EFE supplementationat 500mg/kg DM diets was higher than control group and EFE supplementation at 250 and 750mg/kg. This result confirmed that EFE supplementation at 500 mg/kg DM was the suitable level to enhance fiber degradation and improve energy density and end product of fermentation of TMR with 50% rice straw and 50% concentrate. |
