The objective of this experiment was to evaluate the chemical-bromatological composition and apparent digestibility of ten hybrids of corn (DK265bm3, DK265, HS5, HS6, HTV2, HTV27, Anjou285, Mexxal, Pistachio and Buxxil) planted at INRA (Unité of Génétique Amélioration des Plantes Fourragères, Lusignan-France), in 150 m² areas with three replications. The digestibility study was conducted using sheep fed corn hybrid whole plant silage with three replications. Corn hybrids were evaluated before ensilage using NIRS, and a significant difference (p < 0.05) was observed among treatments for chemical composition. DK265bm3 showed higher values than other hybrids for digestibility of DM, OM, cellulose, NDF and for IVDMD.
