Four trials were conducted to determine the feeding value of whole-plant
forage and grain sorghum silages. In general, growing cattle fed grain sorghum
hybrids (NK2778, Funk's 550, DeKalb 42Y, DeKalb E67) out performed those fed
forage sorghum silages. Only moderate to high grain-content, forage sorghums
(Buffalo Canex, Pioneer 947, Acco 351) gave performances that approached the
grain sorghums. Low grain-content and nonheading forage sorghums (DeKalb 25E,
Funk's G-1990) resulted in the poorest cattle performance. These studies indicate
that grain content of a sorghum silage is the major determinant of cattle
performance and that whole-plant grain sorghums should produce the fastest and
most efficient gains in growing programs.
