Roselle seeds are usually processed or treated with enzymes before feeding to broilers and in smaller quantities. Recently, there has been a growing demand for roselle seed oil, which has resulted in the creation of large quantities of cake, but it is not widely use. The aim of this study was to determine the nutritional composition of roselle seed cake (Hibiscus sabdariffa L.) and its effect on broiler chickens. 100 kg of roselle seed cake was collected from households that extract roselle seed oil. Chemical analyzes were performed on RSC to determine the proximate, mineral and amino acid components. Five isonitrogenic and isoocaloric starter and finisher diets each were formulated, which included the following: CONT: soybean meal-based basal diet, RSC25: basal diet added with 25 % roselle seed cake, RSC50: basal diet added with 50 % roselle seed cake, RSC75: basal diet added with 75 % roselle seed cake and RSC100: basal diet added with 100 % roselle seed cake. Two hundred (250) day old Arbor Acre AA breed were assigned to the five dietary treatments and each treatment consisted of 5 replicates, and each replicate included 10 birds. The design used was a completely randomized design (CRD). The birds received feed and water ad libitum for 56 days. The results showed that the roselle seed cake was high in crude protein, nitrogen-free extract, potassium, phosphorus, iron leucine and arginine, but low in sodium, copper, selenium and methionine. The inclusion of RSC25 and RSC50 in the feed promoted a high growth rate and effective feed conversion. Furthermore, RSC25 and RSC50 as control diet promoted high carcass yield, packed cell volume and high red blood cells count. Internal organs, hemoglobin, erythrocyte indices, white blood cells and their differentials, and the entire serum biochemical indices were similar in all treatments. It can be concluded that RSC is rich in proteins and energy and it can be included up to 50 % in the diet of broilers without negative effects on growth rate and carcass performance.
