Department of Agriculture feeding trials with grazing sheep have consistently shown that the level of supplementation should be set for survival and little more, because beyond that the additional costs of supplementary feeding usually outstrip the benefits from extra production.
Even sheep in the greatest need - autumn lambing ewes in late pregnancy and the early part of lactation before and during the break of season - can be fed less than was thought necessary to achieve acceptable production.
