Summary

Feedlot performance and carcass characteristics were compared when steer calves were fed energy dense diets ad libitum (AL) or restricted (RI) to achieve constant growth rates. AL steers grew more rapidly (P.e.10) than RI steers, 2.93 vs 2.74 Ib per head per day. For the period from 98 days to slaughter (AL = 89 days, RI = 99 days), AL steers consumed more dry matter daily than Rl steers. Restricting intake did not affect feed conversions or total dry matter consumed while in the feedlot. Steers were slaughtered at similar final weights. Intake level did not affect carcass weight, rib fat thickness or rib eye area. RI resulted in depressed (Pc.05) marbling scores and increased (P<.05) percentage KHP. Failure to achieve maximal rates of gain appears to be a primary factor affecting marbling scores in steers 13 to 14 months of age.
