An experiment is described in which folding and sideways creep‐grazing was compared with a rotational grazing management for lamb production at pasture.The experiment was carried out in two years (1957 and 1958) using a stocking‐rate of 7 ewes and 12 lambs per acre from the birth of the lambs until they had all been sent for slaughter.The folding management produced more liveweight gain per acre (955 and 983 Ib.) than the rotational management (870 and 926 Ib.) and the mean carcass‐weights were higher.The biggest differences, in favour of the sideways creep‐grazing system, were in tbe quality of the carcass produced. Folding produced 74% and 77% grade A carcasses and the rotational management 43% and 53%, respectively, in 1957 and 1958.Worm‐infestation was considerably less under the folding management and parasite control appeared to be more efFective where the area reserved for lambs only was not expanded to include ewe‐grazed pasture as the season
