Abstract

1. Egg production ability and its economical aspect were compared among the hens kept under semi-scavenging condition on two feeding systems with four supplementary levels. Commercial balanced feed and cafeteria feeding diet were fed the hens at 40 g, 60 g, 80 g and 120 g/day respectively. Cafeteria feeding diet was composed of 70% mixed feed (40% broken rice, 20% rice polish and 10% wheat bran), 27% soybean meal and 3% oyster shell. 2. The mean feed residue was 4-8 g/day in the hens fed 40 g and 60 g feed group and in 120 g feed group of both feeding system was about 20 g. Body weight gain in the experimental period markedly varied but did not differ among the feed groups. 3. Hen day egg production was highest in the 120 g commercial feed group (55%), followed by the 120 g cafeteria feeding group (45%) and the 80 g commercial feed group (42%). The other feed groups showed 34-37% in hen day egg production except for 27% of the 40 g commercial feed group. Egg quality did not have an intimate relation with the different feed regimes. 4. Regardless of the low egg production ability, the 40 g cafeteria feeding group produced the highest net profit and the 80 g cafeteria feeding group produced the second highest profit. These high net profits were brought from low feed cost. However, the highest income was observed in the 120 g commercial feed group. 5. From these results, it was suggested that under semi-scavenging condition supplemented feeds improve the egg production ability of hens in parallel with the feeding volume although large volume diet decrease large profit.
