Project Title: Rearing strategies for dairy heifers 

Overview: The volume of replacement heifers in the national herd is an indication that the Irish dairy industry is set for further expansion. Therefore, development of an optimum heifer rearing strategy is becoming increasingly necessary; such a strategy must begin shortly after birth and continue until the heifer calves down. In spring 2018 a three-year study commenced at Teagasc Moorepark to investigate the effect of weaning age and post-weaning growth rate on growth performance, fertility parameters, age at first calving and first lactation milk production of the maiden heifer.
