Corn Silage and Corn Silage Plus Small Grain Pasture for Finishing Steers

Georgia Coastal Plain Experiment Station, Tifton 31794

Abstract

A 3-YEAR study was conducted to compare corn silage and small grain pasture used separately and in combination for finishing steers. Each year, yearling steers were started on a full feed of corn silage plus cottonseed meal. When small grain grazing became available, the steers were divided into three comparable groups and placed on treatment. Group 1 was transferred to oat or rye pasture and grazed without supplemental feed. Group 2 was allowed to graze oat or rye pasture and was supplemented with corn silage fed to appetite once daily. Group 3 remained in drylot and was finished on corn silage and cottonseed meal. Steers fed corn silage to appetite plus small grain pasture consumed one third as much silage as steers in group 3 when allowed two thirds as much grazing as steers in group 1. Average daily gains were not different (P>.05) among years or treatments. Steers fed only corn silage and cottonseed meal produced less carcass weight per unit of live weight (P<.05) but had more desirably colored carcass fat (P<.05) than steers which grazed oat and rye pastures. Average returns to capital, land, labor and management were $2.97, $11.07 and $24.12 for steers in groups 1, 2 and 3, respectively.
