AbstractMature sheep which had had a previous history of continuous undernutrition from conception to 4½ years of age (L) produced less wool than sheep well nourished throughout life (H), whether fed at the same level per unit liveweight 0.73 or fed ad libitum. However, the maintenance requirements of the two groups of sheep were similar. When feed was offered ad libitum, the L sheep, which were much smaller at the start of the experiment, had intakes similar to the H sheep, gained more weight, but produced less wool than the H sheep. Efficiencies of wool growth were similar when intakes were restricted, but in animals fed ad libitum there was a suggestion that the L sheep were less efficient than the H sheep.
