The aim of the study was to evaluate the effect of new introduced technologies for corn silage harvest (used the corn cracker concept named MCC MAX and MCC Shredlage) on qualitative parameters of whole-plant chopped material. The kernel processing, proportion of chop length analysis and effect of corn silages processing on rumen degradability of nutrients were evaluated. We observed the highest kernel processing and also the highest content of physically effective fiber in corn silages produced by technology Shredlage. Compared with classical corn cracker concept, the chopped material, produced by MAX and Shredlage technologies, had the higher rumen degradability of dry matter, neutral-detergent fiber and starch in both dry matter content levels.
