Abstract

The dry matter content increase due to the extension of the harversted period beginning and the kind of hybrid used can affect the starch digestibility and voluntary intake of ruminants. Therefore, this study aimed to determine the best corn hybrid and processing type of silage corn, and evaluate the possible effects on starch digestibility and voluntary intake of lambs. It was used 24 Santa Inês lambs with average age of three months and average initial weight of 25.0 kg. The experimental design was completely randomized in a 2x2 factorial design (dent and flint hybrids; crushed and not crushed). The processing of the dent hybrid resulted in less dry matter intake (0.583 kg/day) associated to higher total digestibility of dry matter and starch, 68.21 and 95.33% respectively. Thus, the processing of corn plants used for silage should be performed on hybrids with the dent grain texture to provide the best digestibility of silage to lambs.
