Hill gimmers typically perform below the flock average and are reluctant to take supplementary feed. This paper reports an attempt to evaluate the effects in the first breeding season of training young flock replacements to eat supplementary feed in the form of either concentrate pellets or feedblocks.

Four hundred and fifty-five ewe hoggs were allocated to two groups on return from away-wintering on 1 April. Untrained hoggs (U) were put to the hill immediately. The remainder were trained to feed (T) for one week before rejoining their contempories. Training and subsequent mating treatments are summarised in Table 1.
