Abstract

Replacement heifers from 2 different calving herds (March and May) were fed ad libitum hay and 4 lb of supplement/day, or were allowed to graze meadow and received 1 lb of supplement/day from mid-January to mid-April prior to both breeding seasons. Heifers from both calving herds that received hay had a greater average daily gain during the treatment period compared with meadow grazing heifers. However, heifers grazing meadow experiencedcompensatory gain during their respective breeding season, resulting in similar body weights at pregnancy diagnosis for March-calving heifers. The proportion of heifers that attained pubertybefore breeding and became pregnant was similar between the treatment groups in both herds.
