Chemical composition and energy value of corn and wet corn grain silage for poultry

Abstract

The objective of this study was to evaluate the apparent metabolizable energy (AME), AME corrected for nitrogen retention (AMEn), true metabolizable energy (TME) and TME corrected for nitrogen retention (TMEn), and respective metabolizability coefficient (AMC) of corn and high moisture corn grain silage (HMCGS) with 50 and 100 days of ensilage and different inoculant levels for poultry. For determination the values of energy, the total excreta collecting method was used, which 144 broiler chicken Ross 308, 21 days old, were distributed in a completely randomized design. Differences were not observed (P>0.05) for metabolizability coefficient. It was concluded that the values of AME, AMEn, TME and TMEn of corn were 3680, 3588, 3748 and 3735 kcal/kg respectively and the values of AME, AMEn, TME and TMEn of HMCGS ranged from 3477 to 3881, 3401 to 3769, 3573 to 3985 and 2374 to 2649 kcal/kg, respectively.
