ResumenFor each of the Welsh Mountain and Beulah genotypes, 78 wether lambs were offered either continuous ad libitum feed or a period of food supply restricted to maintenance (84 days) followed by ad libitum feeding. Lambs of the larger Beulah genotype had a greater proportion of carcase in their liveweight (P<0.001), greater rate of liveweight gain (g/day P<0.05) but a greater intake (g/kg LW/day P<0.001). Rates of liveweight gain and efficiency of food conversion were significantly greater during the post-restriction growth phase as compared to continuous ad libitum growth (P<0.001). These effects of dietary treatment were consistent in the two breeds.
