Abstract

Eighteen spring-calving heifers were paired by expected calving date and assigned to treatment. Treatments were a high undegradable intake protein supplement (CON) or one based on dry corn gluten feed (TRT). Heifers were fed to consume low-quality hay ad libitum. Supplement type did not affect body condition, milk production, or calf ADG. TRT heifers lost less weight than CON heifers. There was no effect of supplement on forage intake. Intake changed cubically with respect to calving; decreasing 17% during the three weeks prior to calving, and increasing 18% the week after calving.
