Numerous studies have evaluated the impact of maize hybrid on chemical composition and digestibility of silage (Hetta et al. 2012). The combined effects of weather and genotypes on maize chemical composition were considered by Kruse et al. (2008), while Darby and Lauer (2002) investigated the effects of hybrids on chemical composition development as crop maturity progressed through to harvest time. The objective of our study was to confirm the declared properties of the selected two maize hybrids two years, especially in terms of amylase-treated neutral detergent fibre digestibility (aNDFD) in silage, which could strongly influence the result of the calculation of the energy value of the fodder.
