Three sorghum hybrid types were used to make six silages in the fall of
1983. Eight silage rations were compared using 160 steer calves in an 84-day
growing trial. Using forage sorghum silage as a base (100), grain sorghum silage had
a feeding value of 133, and nonheading sorghum silage 89, when evaluated for
comparative rates and efficiencies of gain. Silages from concrete stave silos
produced faster and more efficient steer gains than silages from Silopress® bags.
Rolling the grain sorghum silages at feeding time to break 95% of the grain
significantly improved steer performance. The feeding value of corn silage was not
enhanced by processing.
