Abstract

EFFECT OF FEED RESTRICTION AND DIFFERENT CRUDE FIBER SOURCES ON THE BORILER PERFORMANCE. The research aim was to determine the performance of Lohman strain broiler were given by food restriction of 20 percent and 10 percent levels of crude fiber from different fiber sources originated from coffee peel, rice bran and coconut pulp. This research was carried out in a poultry house at the Faculty of Animal Husbandry, UNSRAT Manado, during 6 weeks using 48 unsex Lohman strain broilers at 21 days old. The research method was using a Completely Randomized Design (CRD) based on factorial pattern (2x4). Each treatment combination was repeated 3 times. Factor A was a feed restriction consisting of feed without restriction (A0) and restriction of 20% feed for 8 days (A1). Factor B was a source of fiber consisting of control (B0);coffee peel (B1); rice bran (B2) and coconut pulp (B3). In this study, the were 8 treatment combinations of A0B0, A0B1, A0B2, A0B3, A1B0, A1B1, A1B2 and A1B3. Application of feed restriction and source of fiber  were applied during days of 21th to day of 28th. The birds were fed commercial feed until 42 days of age. The variables measured were feed consumption, body weight gain and feed conversion. The results showed that the restriction of feed and different fiber sources had a significant effect (P <0.05) on feed consumption, body weight gain and feed conversion. The results of this study can be concluded that the restriction of feed by 20 percent for 8 days with a source of crude fiber originated from coconut pulp in feed gave the best response compared with crude fiber originated from coffee peel and rice bran on the performance of the Lohman strain of broiler.Keywords: Broiler, feed restriction, crude fiber
