Effects Of Dietary Energy Density And Frame Size On Performance And Body Composition Of Feedlot Steers, Claudio C. Ribeiro-Filho, Allen H. Trenkle, Daniel D. Loy

Beef Research Report, 2003

Thirty-six steers were sorted by frame size and individually fed diets containing 2.4, 2.7, or 3.0 Mcal of ME/kg of DM to evaluate the effects of dietary energy density and animal frame size on performance and body composition. Frame size did not have an effect on performance or body composition. Steers fed the 2.4 or 2.7 Mcal/kg diet had a higher feed intake than those fed the 3.0 Mcal/kg diet, but they were less efficient. The results indicated that steers fed the diet with higher energy concentration deposited more fat earlier ...
