ABSTRACT This research was undertaken to evaluate energy utilization and blood metabolites status of male Indonesian local sheep involving nutrient balances and urea techniques. Factorial randomized completely design was used in this study using 16 growing male local sheep. Factor A was breed which consisted of 8 gamt sheep (av.BW 14.90 kg) and 8 jonggol sheep (av.BW 13.60 kg). Factor B was ration which received Indigofera sp. and sproutbean ration of ad libitum fed. The ration offered were pellets containing CP around 16% and energy 15,6 MJ GE/kg. Energy balance and blood metabolites studies were conducted during thee-months trial. Intake, digestibility, urinary and metabolism parameters were measured based on total collection method. Methane energy was measured by rusitec technique and methane gas production multiplied by calory equivalent value of methane. Energy retention (RE) was measured by urea space technique. Heat production was calculated from ME-RE. Plasma glucose, cholesterol and urea-N were measured by using spectrophotometry. Result showed that there were significant different of energy intakes, digestibilities and metabolism among the rations. Animals fed with sproutbean ration has higher energy utilization compared to Indigo/era sp ration. There were no significant different for all blood metabolite parameters among breed and its interaction between combination treatments. It was concluded that both rations were good for local sheep.
