Abstract
Objective: The objective of this experiment was to compare the subsequent growth performance and carcass impacts of a high-energy diet limit-fed at 2.2% of body weight (BW) or a traditional roughage-based diet fed ad libitum during the growing phase.
Highlights
Previous research suggests limit feeding a high-energy diet to growing cattle during the growing phase may have carryover effects on both finishing growth performance and carcass characteristics
The two backgrounding diets included: (1) 45 Mcal of net energy for gain (NEg) per 100 lb of dry matter (DM) fed for ad libitum intake (45AL), or (2) 60 Mcal NEg per 100 lb of DM limit-fed at 2.2% of body weight (BW) daily on a DM basis (60LF2.2)
Three hundred seventy crossbred heifers [initial body weight (BW) = 496 ± 44 lb] previously used in a 90-day growing and receiving study at the Kansas State University Beef Stocker Unit were transported to a commercial feedlot (Pratt Feeders, Pratt, KS) for finishing where cattle were fed a common diet
