%X At the end of 23 weeks the mean daily dry matter intake of Merino weaners was 190 g of poultry litter and 235 g of wheat. The mean weekly body weight gain, 210 g per sheep, was not significantly different to weaners that consumed a mean daily dry matter intake of 365 g of wheat grain and gained 180 g weekly. The mean digestible organic matter content of wheat and poultry litter were calculated to be 88 and 31 per cent respectively. Weaners fed wheat only were not supplemented with limestone (1.5 per cent) for 13 weeks by which time two of the eight weaners had serum calcium levels below 8 mg per 100 ml. One of these weaners had gained weight, the other had lost weight and died three weeks after limestone supplementation. The addition of limestone did not increase the mean serum calcium levels significantly, but at the end of the trial all weaners had levels above 8 mg per 100 ml. ' Serum glutamate oxalacetate transaminase and bilirubin concentrations were higher for weaners fed wheat-litter mixture, but below levels normally associated with liver dysfunction. Reasons for caution in the use of poultry litter in the manufacture of commercial feedstuffs for ruminants are discussed.
