Twenty-four Holstein cows were used to
evaluate the effects of processing methods on
grain sorghum utilization by lactating dairy cows.
No difference was observed in the utilization of
steam-flaked grain sorghum and pelleted grain
sorghum obtained by adding water to finely
ground grain sorghum prior to extrusion and
oven drying at a temperature of 200EF.
Extensive processing (pelleting or steam-flaking)
improved feed efficiency relative to dry rolling.
Cows fed diets containing more extensively
processed grains ate less feed but produced the
same amount of milk as cows fed diets
containing dry-rolled grain.
