Popis: A study was carried out to compare the use of blood meal and fish meal as protein sources in single phase feeding of broiler chickens. Three isonitrogenious and isocaloric diets containing between 20.5 to 21.1 % CP and 3440 to 3454 kcal/kg ME were formulated. The control diet contained none of the animal protein sources while the other two diets contained blood meal and fish meal at 6%, respectively. After six weeks of straight feeding, data were collected on feed intake, weight gain and feed conversion ratio was calculated. Carcass characteristics and cost benefit were also calculated. The results indicated that birds fed fish meal based diet consumed more feed (p< 0.05) than those on control diet, while intake of those on blood meal based diet was an interphase between the control and fish meal based diet groups. The birds fed fish meal based diet also recorded higher (p< 0.05) daily weight gain than those on control and blood meal based diets. Feed conversion ratio was better in the group fed fish meal based diet than those fed the control diet, but similar (p> 0.05) to the group fed the blood meal based diet. The dressing percentage of the birds was similar (p>0.05) in the control and blood meal based diet groups, but they were higher (p
