This study was conducted to compare in vitro rumen fermentation characteristics among corn grains imported from America, Brazil, Argentina and Ukraine A and Ukraine B. Two Holstein steers, each surgically fitted with a ruminal cannula, consuming total mixed ration were used as rumen fluid donors. In vitro rumen fermentation experiments were performed in a completely random design which included a control (no corn) and treatments with 3.0 g of corn from different geographical origins, i.e., America, Brazil, Argentina, and Ukraine A and Ukraine B, respectively. Ruminal pH, ammonia-N, volatile fatty acid (VFA) and total gas production were measured at 0, 1, 3, 6, 12, 24 and 48 h post-incubation, respectively. No differences (p > 0.05) in mean ruminal pH appeared among the treated groups, however, ruminal pH patterns differed; i.e. corn treated groups had dramatically lower pH compared with control during the entire incubation period. Similarly, no different patterns between the groups in ammonia-N (p > 0.05) appeared until 6 h post-incubation. Unexpectedly, higher ammonia-N concentration for control than that for the corn treated groups appeared after 12 h post-incubation despite that for all groups increased. Total VFA was similar between the groups until 6 h post-incubation, but VFA after 12 h post-incubation was different (p < 0.05), i.e. VFA for corn from Argentina, Ukraine A, Ukraine B, and Brazil were comparatively higher than for America. Overall, data in this study showed that the corns of different origins may have different feed values to ruminants despite having similar chemical compositions.
