We investigated the effects of whole-grain hulled rice feeding on ‘Hakata Ichibandori’ chickens economics. Approximately 6,000 ‘Hakata Ichibandori’ chickens were divided into an experimental group and a control group. The 50% corn in the formula diet for the experimental group was replaced with whole-grain hulled rice and consumed during the later period of fattening. The formula diet for the control group contained 60% corn with no rice. The following results were obtained : (1) All groups suited the ‘chickens’ taste and the ‘chickens’ health was good. (2) The average body weight did not differ between the both groups. (3) The feed conversion rate tended to be better in the experimental group. (4) Cost economics in the experimental group was higher than in the control group. (5) The bedding moisture of the chickens was significantly lower in the experimental group than in the control group. (6) The feed rice was adapted to the automatic feeding system. We suggest that in the field demonstration, whole-grain hulled rice feeding did not significantly influence the productive performance and feeding management, or increase the economic benefit of ‘Hakata Ichibandori’ chickens.
