Experiments were conducted for monthly periods during the spring and summer and autumn of 1982-83 with lambs fed on pastures from limed (pH 6.1) and unlimed (pH 5.5) areas. Lambs were offered herbage allowances 1, 2, 3, 4 or 5 kg DM/d on both limed and unlimed areas (10 groups of 10 lambs). Pasture composition remained similar between the 2 areas as did in vitro digestibilities of the pasture on offer. Limed pasture showed an increase in Ca and Mo and a decrease in Mn compared with the unlimed. Lamb live-weight gains were similar between limed and unlimed groups at all levels of herbage allowance over the 3 seasons suggesting that herbage quantity rather than quality was the major factor affecting the growth rate of the animals.
