This was in a grazing trial with corn on a dairy farm. I will say that
the main thing we learned from this trial is to NOT GRAZE CORN WITH DAIRY
CATTLE! Some of the symptoms we saw included, low dry matter intake,
acidosis, and a drop in production. Our main goal with this trial was to
determine what crop would be the best to plant while trying to replace the
fescue.

Results:
Corn- 40% utilization, poor cow performance, not enough dry matter intake,
acidosis, low production.
Brown Midrib Sorghum - 3 grazings, yield estimate at 8 tons per acre, cow
performance and utilization - excellent
Fescue - GONE!
Due to the problems with the corn, we felt that the production data on the
herd would not be a good indicator of the sorghum performance.
