The objective was to evaluate diets containing different inclusion levels of inert palm fat as a feed supplement on nu- trient intake and biochemical parameters of developing goats. Sixteen kids (Anglo Nubian x Saanen) with a mean age of 60 days and a live weight of 18.66 kg were used. The diet consisted of sorghum silage and fat included concentrate. Each proportion of inclusion consisted of a dietary treatment: 0; 25; 50 and 75 Grams/animal day of EnerFAT®. The animals were fed at 08h and 16h with diets formulated following NRC (2007) recommendations. Blood was collected by jugular venipuncture using vacutainer® tubes with clot activator. The concentrations of energy metabolites, protein and liver enzymes were evaluated. The experiment was conducted in an entirely randomized design with repeated measures in time. The data were evaluated by regression study considering significance P<0.05. There was a positive linear effect for DM, MMC and MOC during the experimental period (P<0.05). Fructosamine and glucose showed quadratic effect for experimental period. There was interaction between treatment and period for cholesterol, triglyce- rides, HDL and VLDL variables, as well as for TC/HDL and LDL/HDL ratios. GGT showed a quadratic effect for the experimental period. UA showed a positive linear increase among treatments. AU and AL showed a quadratic effect for the period and CR suffered a negative linear effect for period. EnerFAT® increases the energy intake of the diet, changing the values of protein metabolites of developing goats, keeping them above the ideal values for the species.
