Abstract
Male Merino lambs 110-117 days old in 7 groups of 12 were fed for 5 months on green lucerne, straw and a concentrate mixture with 30, 40 or 50% dried deep litter of broiler chickens or laying hens. Mean daily gain was with no litter 178, with increasing amounts of litter of broiler chickens 190, 220 and 213, and of laying hens 217, 223 and 210 g. Intakes/kg gain were for oat feed units 6.1, 5.3, 4.7, 4.7, 4.7, 4.7 and 4.9 kg, and for digestible crude protein 793, 727, 631, 649, 747, 610 and 670 g. Dressing percentage, 48.7 to 49.9, proportion of lean, 63.3 to 64.8%, and of fat, 16 to 16.2%, in the carcass were similar. Myoglobin in meat from lambs given poultry litter was 9.4 to 9.6 and total pigments were 11.1 to 11.9 mg/100 g against 8.0 and 9.6 mg/100 g with no poultry litter in the diet, probably because of the high contents of Fe and Cu in the litter.
