Theaim of thepresentstudy wasto evaluate the dietary effect of an enzymatic complex on the growthperformancevariables, blood parameters,and economic viabilityof piglets. To achieve this,we used80 piglets (40 castrated males and 40 females)in a 2 ×2 factorial design following a randomized blockexperimentaldistribution, with twolevels of metabolizable energy (adequate: 3206.09 and low: 3005.45 kcalkg-1) and twoenzyme levels (0 and 50 gton-1). The results showed no significant difference between treatments inthe growthperformance variables or blood parameters of piglets. The economic viability, economic efficiency index,and costindex were improved when we used a diet with alow energy supplemented withthe enzyme complexas comparedto other experimental diets. Thus, we concludedthat enzyme complex supplementation canmaintain growthperformance and blood parameters inpiglets even whenthey arefed low energy diets.Moreover, this could reduceproduction costs.(AU)
