Mesquite pod meal in elephant grass silages - doi: 10.4025/actascianimsci.v35i3.12506
This study evaluated the chemical composition and in vitro dry matter digestibility (IVDMD) of elephant grass silages at different growth stages (70, 90 and 110 days), with the addition (0, 5, 10 and 15%, on a fresh matter basis) of mesquite pod meal. A completely randomized design (CRD) was used in...

| Sumario: | This study evaluated the chemical composition and in vitro dry matter digestibility (IVDMD) of elephant grass silages at different growth stages (70, 90 and 110 days), with the addition (0, 5, 10 and 15%, on a fresh matter basis) of mesquite pod meal. A completely randomized design (CRD) was used in a factorial arrangement with four replications. PVC pipes 100 mm in diameter were used as experimental silos. After 30 days of ensilage, samples were taken from the open silos to determine chemical composition and IVDMD. The inclusion of mesquite pod meal (MPM) increased (p < 0.01) the concentrations of DM and CP. No interaction (p > 0.01) was detected between MPM concentrations and elephant grass cutting age for DM, CP and NDF contents in the silages. A decrease (p < 0.01) was observed in NDF, ADF and MM concentrations with the inclusion of MPM. There was a linear increase (p < 0.01) in IVDMD with increasing levels of MPM; and IVDMD decreased (p < 0.01) with increasing cutting age of the elephant grass. The inclusion of mesquite pod meal contributed to improve the chemical composition and digestibility of silages. |
