Two groups of ewes, each containing single and twin lambs, were folded over a ‘worm‐free’ pasture, with a creep provided for the lambs, allowing them to graze ahead of the ewes. The lambs of one group received supplementary feeding. Higher growth rates of the Iambs were recorded than those previously reported by other workers. The growth rates of twin lambs were improved more than those of singles and the lambs receiving supplementary feeding gained at a significantly faster rate than those on pasture only. Faecal egg counts indicated that worm infestation in the lambs was maintained at a very low level.
