In the present study, the effect of feeding of Euglena (Euglena gracilis) on the growth performance and meat quality in Hinai-jidori chickens were examined. Day old twenty six Hinai-jidori female chicks were divided into three groups, control group was fed only mixed feed and Euglena groups were fed mixed feed in which added 1.25% Euglena (1.25% group) or 2.5% Euglena (2.5% group) till 23 weeks of age. The body weight and daily weight gains of 1.25% and 2.5% groups at 4 weeks of age were significantly higher than those of control group. At 23 weeks of age, there were no significant differences in the body weight and daily weight gains. 1.25% group had significantly higher lauric acid, pentadecanoic acid and margaric acid contents, and 2.5% group had significantly higher lauric acid, myristic acid, pentadecanoic acid and docosahexaenoic acid contents than control group. These results suggest that Euglena does not have great effect on the growth performance in Hinai-jidori chickens, and increases fatty acid contents such as docosahexaenoic acid in the thigh meat.
