THE EFFECT OF FEED RESTRICTION AND DIFFERENCE SOURCE OF CRUDE FIBER ON LIVE WEIGT, CARCASS WEIGHT AND COMMERCIAL PIECES OF BROILER WITH LOHMAN STRAIN. The objective of research was to determine the effect of feed restriction and source of different crude fiber on live weight, carcass weigth and commercial pieces of broiler with Lohman strain. The material used was 24 broilers. This research was using a Completely Randomized Design (CRD) in Factorial pattern of 2x4 with 3 replications. Feed restrictions were carried out at the age of 21 to 28 days old, after restrictions on broilers were fed commercial ration ad libitum feed until a time periode of 42 days. As a factor A was restricted feeding consisted of without restrictions (A0), and 20 percents restricted ration (A1). A factor B was source of crude fiber consisted of commercial feed (B0), commercial feed with coffee hull meal (B1), commercial feed with rice bran (B2), and commercial feed with coconut pulp (B3). The data analyzed used variance analysis and Tukey test to determine which one of treatment was significantly different from each other. The variables measured were live weight, carcass weight and percentage of commercial pieces consist of breast, thigh, drumstick, wing and brisket. The results showed that the combination treatment of feed restriction and source of crude fiber in feed gave a very significant different effect (P <0.05) on live weigth, carcass weight and commercial pieces of broiler with Lohman strain. The 20 percents restriction feeding with coconut pulp as a source of crude fiber gave best results on live weight, carcass weight, and commercial pieces of broiler with Lohman strain.
