Replacement heifers were developed using corn stalks (Experiments 1 and 2), winter range (Experiment 1), or a dry lot (Experiment 2) with or without a high energy supplement around breeding. Corn stalk development reduced ADG and the percentage pubertal prior to breeding; however, neither first service conception nor pregnancy rates were affected. High energy supplemental nutrition around breeding tends to improve first service conception. Corn stalk development does not appear to negatively impact reproduction, although it resulted in lighter calf birth weight compared to winter range.
