Calves born in late September to early October in 1956, 1957 and 1958 were reared at pasture. They were fed milk substitute, supplemented in some cases with concentrate feeding‐stuffs.The losses due to outdoor rearing were low, and calves made satisfactory gains in weight. By rearing at pasture, a considerable saving was effected in the weight of concentrates and hay consumed, while no marked response to the feeding of these supplements before weaning was found. Animals born in the autumn of 1957 and reared on this system reached 10 cwt. in less than 24 month
