Abstract
Crops of oats (Avena sativa), lupins (Lupinus angustifolius) and field peas (Pisum arvense) harvested in January 1974 yielded respectively 1748, 1431 and 121 4 kg DM grain and 6880, 351 0 and 3350 kg DM stubble ha-1. After harvest the stubbles were grazed for 14 weeks with crossbred ewes and wethers at 11.25 and 22.5 ha-1. Straw from each stubble was of uniformly low digestibility (30 per cent), but legume straw was consistently higher in N than oat straw (1.4 vs. 0.77 per cent N). A strong preference by sheep for green material resulted in most of the crop residue remaining at the end of the experiment. There was a small liveweight gain at the tower stocking rate and a weight loss at the higher stocking rate (P < 0.01). Sheep grazing pea stubble at the lower stocking rate gained 3 kg more than those on oat stubble but the differences were not significant (P< 0.05)
