چکیده
Abstract The backgrounding period is a post-weaning management strategy to add weight and build the health status in beef calves. This phase used prepare calves enter next of production supply chain. Weaning methods can be strategies reduce calf morbidity mortality feedlot. objective this study was assess growth performance based on weaning subsequent using commonly forage-based diets by Alabama producers. A two-year conducted 427 steers (n = 216, year 1, average BW 306kg; n 213, 2, 294kg). Steer from three Auburn University research farms were randomly assigned weights one different method groups: fenceline weaning, nose-flap or abrupt weaning. After brought centralized farm began 60-d where they randomized according previous management, origin body nutritional 3×3 factorial design: cool-season baleage (oats, ryegrass crimson clover) 1% dried distillers’ grains (DDGS), bermudagrass hay DDGS, grazing mixed warm-season annuals DDGS. Body collected d 0, 30 60 phase. In both years, weaned had greatest daily gain (year 0.76 kg/d; 1.03 P 0.0225) first days regardless diet type. Calves fed hay-based also greater 0.78 1.24 < 0.0001) than groups backgrounding. From each year, least 0.19 0.42 0.0001).

Performance of Beef Calves
These results support the earlier findings by Dr. Bill Kunkle and his research involving limitcreep supplements based on cottonseed meal and salt mixtures. Calf performance responses, as measured by the added gain realized by creep supplementation, are highly variable and cannot always be described by amounts of creep feed consumed. This variability has large and direct impacts on the cost effe...

Over 3 yr, 250 calves (236 kg initial BW; 133 steers and 117 heifers) were used to compare a low-input pasture backgrounding system (PAST) to a highinput drylot system (DLOT) to evaluate performance and profit during the backgrounding (BACKGRD; weaning to 42 to 45 d) and finishing (FINISH; end BACKGRD to slaughter) phases. Calves were randomly assigned to PAST or DLOT treatments during BACKGRD....
