Whole-plant forage, grain, or nonheading sorghum silages for growing cattle

摘要

Three sorghum hybrid types were used to make six silages in the fall of1983. Eight silage rations were compared using 160 steer calves in an 84-daygrowing trial. Using forage sorghum silage as a base (100), grain sorghum silage hada feeding value of 133, and nonheading sorghum silage 89, when evaluated forcomparative rates and efficiencies of gain. Silages from concrete stave silosproduced faster and more efficient steer gains than silages from Silopress® bags.Rolling the grain sorghum silages at feeding time to break 95% of the grainsignificantly improved steer performance. The feeding value of corn silage was notenhanced by processing.
