The objective was to evaluate the effect of additives through acidification of diets with blends of organic acids in diets for pigs from 21 to 49 days old, were used 720 pigs weaned at 21 days old, with average initial weight of 5,81 kg, distributed in randomized block design, with six treatments and eight replicates of fifteen animals each. Treatments were: CONT = diets acidified with blend of organic acids, ANT = Diet T1 + Colistin sulphate (60 ppm), PRE = Diet T1 + Prebiotic one (2.00 kg / ton.), PRE 2 = Diet T1 + Prebiotic two + (2.00 kg / ton.), PRO = Diet T1 + Probiotic (0.40 kg/ ton.) and FIT = Diet T1 + herbal extract (0.20 kg / ton). There was no effect of treatment on average daily weight gain, average daily feed intake and feed conversion in the period from 21 to 35, 36 to 49 and 21 to 49 days of age, except in the period from 36 to 49 days old where the average daily weight gain of piglets was higher in CONT, ANT, PRE1, and pre2 PRO. The use of additives such as antibiotics, prebiotics and probiotics associated with the blend of organic acid in diets for piglets weaned at 21 days old, showed higher average daily weight gain in piglets from 36 to 49 days old.
