A digestion study evaluated three corn silage hybrids for growing crossbred steers. The three hybrids were: a standard corn silage hybrid which served as the control, a brown midrib hybrid (bm3), and an experimental bm3 hybrid with a softer endosperm. Both bm3 hybrids had greater organic matter and fiber digestibility compared to the control corn silage. However, no differences were observed between the two bm3 hybrids. Rumen pH was reduced for BM3 and BM3-EXP compared to the control suggesting greater rumen fermentation. In vitro gas production was increased for the bm3 hybrids compared to the control further supporting greater rumen fermentation.
