Abstract
The objectives of this study were to determine the effect of preweaning creep feeding behavior on postweaning feeding behavior, performance and carcass characteristics. Steer attendance at creep feeders was categorized as FREQUENT (attending greater than 80 percent of days) or INFREQUENT (attending less than 80 percent of days). Steers that attended the creep feeders more frequently ate more meals and spent more time eating during the first 28 days of the finishing period, compared with infrequent steers.
