Effect of replacing alfalfa hay with Leucaena leucocephala (L. Leucocephala) leaves on in vitro gas production, digestibility and in situ degradability in buffalo

. This study was performed to investigate the effect of replacing alfalfa hay by L. leucocephala leaves in proportions 25, 50 and 100% on vitro gas production (GP) parameter, digestibility situ degradability buffalo. Results showed that volume GP at 2 12 hours after incubation significantly affected with leaves. In organic matter (OMD) differed between treatment as it declined increasing substitution rate from 25 100%. The microbial crude protein (MCP) treatments greatest 589 599 mg g-1 dry (DM) when replaced 50%. DM (IVDMD) increased 50% replacement rate. Moreover, substituting had a significant parameters. insoluble but potentially degradable fraction (B) potential (A+B) for contain effective (ED) different dietary leucocephala. conclusion, can substitute buffalo rations without rumen efficiency.
