| Abstract;This study was carried out to examine which of intravenous glucose or acetate would be rapidly oxidized to CO2 in growing chickens fed a semi-purified diet. 13C Enrichment of respiratory CO2 in chickens intravenously single-injected with [1-13C]sodium acetate sharply increased and reached the peak level within 30-40min, then almost returned to the initial level by 170min. On the other hand, the peak level in chickens intravenously injected with D-[U-13C]glucose was observed at about 100min and did not return to the initial level even at 4h. The peak level of 13C enrichment in chickens injected with [1-13C]sodium acetate was about 2.3 times higher than that in chickens injected with D-[U-13C]glucose. The rate of 13C recovered in the respiratory CO2 for 4h tended to be higher in chickens injected with [1-13C]sodium acetate than in those injected with D-[U-13C]glucose, although the difference was not significant. Rapid appearance of 13C in the respiratory CO2 from [1-13C]sodium acetate more than D-[U-13C]glucose suggests that cecal acetate is utilized as effective as dietary glucose in the chicken body.
