Abstract:The study was conducted to determine the use of fish oil as by-product of fish canning factory in diet on the performance and lipid profiles of native chickens. The experiment used 100 native chicken with an average initial body weight of 48,9 gram ( sd + 9.9), was used in this study for 8 weeks experiment.These were arranged by a completely randomized design with 5 treatments, 5 replications and 4 hens in replication each. The diets were: R0 = 100% Based Diet (BD) + 0% Fish Oil (FO); R1 = 98.5% BD + 1.5% FO; R2 = 98% BD + 2% FO; R3 = 97.5% BD + 2.5% FO; R4 = 97 % BD + 3% FO. Feed and water were provided ad libitum. Variables were performance parameters and lipid profiles. Results showed that fish oil inclusion in diets were significantly increased feed intake, body weight gain, carcass percentage, liver, breast and thigh weight, and decreased blood cholesterol, carbohydrate and meat cholesterol, and also tended to decrease abdominal fat. However, there were no affected on feed conversion, water, protein, fat and ash of breast meat. It can be concluded that the use of fish oil in diet up to 3% could improved performance parameters of native chickens.
This study aimed to evaluate the performance and carcass quality of local chickens given by dietary inclusion, composing of papaya (Carica papaya L.) leaf powder. The experimental free-range chickens used 200 chickens, by the age of 16 weeks and average body weight of 780.58±9.34 gr. Feed was made from corn, rice bran, fish flour, concentrate, and papaya leaves. The research applied Completely Randomized Design (CRD) with 5 treatments and 8 replications. The treatments comprised of R0 = 100% based diet (BD) + 0 % papaya leaf powder (PLP), R1 = 97% BD + 3 % PLP, R2 = 94 % BD + 6 % PLP, R3 = 91 % BD + 9 % PLP, and R4 = 88 % BD + 12 % PLP. Parameters were final weight, carcass weight, and carcass percentage. The result showed that feather performance and carcass quality were not significantly different (P 0.05) against final weight (gr), carcass weight (gr) and carcass percentage (%). In conclusion, papaya leaf can be used as dietary component in feeding to improve carcass quality without negative impact on performance of productive local chickens.
