SUMMARY

Two layer trials were conducted to examine the possibility of using palm oil sludge (POS) or palm oil mill effluent solid (POME Solid) in layer diets. The inclusion levels were 0, 5, 10, 15, 20 and 25% in the first trial. Each diet contained 18% crude protein and 11.3 to 11.5 MI/kg (2,700 to 2,750 kcal/kg) metabolizable energy. In the second trial, 6 diets containing 10 or 20% POS with either lower energy 10.9 MJ/kg (2,600 kcal/kg) or with additional lysine and/or methionine were formulated. Twenty-nine weeks old Hisex Brown layer were used in these two trials for a period of 52 weeks. Result indicated that the optimum inclusion level of POS was 10% with addition of DL-methionine or DL-methionine + lysine which resulted in favourable feed intake, egg production, feed efficiency and egg quality which were comparable to those of corn-soybean control diet. The adverse effect from diets containing rnore than 10% POS could not be remedied by supplementary lysine and methionine.
