Abstract: The effects of replacing boiled sorrel seed meal for soyabean in broiler diet was investigated in an eight week feeding trial. Five diets were fed to 200 day-old Anak-2000 broilers chicks in groups of 40 chicks per diet with 3 replicates of 10 chicks each in a completely randomized design. The diets consisted of a control based on soyabean meal as major protein source and 4 other diets, in which sorrel seed meal was replaced at 0, 15, 30, 45 and 60% respectively. Data were collected on the growth performance, nutrient digestibility and carcass characteristics. There was no significant (p>0.05) dietary effects on final weight and daily weight gain. Feed intake was significantly (p<0.05) higher in treatments receiving sorrel seed meal except for finisher phase where the control diet tend to be higher than treatments 1 and 2. Feed Conversion Ratio (FCR) was better for treatment 4 (45%) compare to other treatments on the starter diet while treatment 2 (15%) had better FCR on the finisher phase. The overall nutrient digestibility was positive except for crude fibre digestibility where treatment 3 (30%) had 45.11%. The result of the carcass characteristics shows that there were significant differences (p<0.05) for all the cut-parts observed. Treatment 5 had higher weight than the other treatment groups except for drumstick, breast muscle, feather weight, head, gizzard and spleen where treatment 4 was higher.
