Considering corn hybrids grown in Brazil are primarily flint-endosperm cultivars(Correa et al 2002), rehydration and ensiling of dry com has been used for increasing starch digestibly, as an alternative to other corn processing such as HMC Additionally, processing of HMC has been limited by machinery availability excessive during the corn bar vest period, which could delay com harvest. Delayed harvest, and the corresponding increase of DM ntent of corn, may process and reduce et al. DM disappearance for HMC and REC after 28-d fermentations Therefore, rehydration and ensiling of dry com may be an alternative in areas where HMC harvest and fermentation are compromised by weather conditions(eg, excessive rain fall, freezing temperatures andlor limited machinery availability. In addition, the used ofREC mightbe an opportunity for storing corn grains during periods of lower prices. However, REC benefits such as increase of ruminal in situ(Arcari et al. 2016). and in vitro disappearance(Ferraretto et al. 2015)and total in vivo apparent digestibility(which was also observed in present study ofstarch from REC compared dry corn should be evaluated under the operational and economicperspec tive of each dairy farm. However, further studies are necessary to evaluate the practical and economic implications ofthe use of other varieties of corn, levels of processing and implementation of rehydration and ensiling technique in the duiry systems.
