Abstract:	The study aimed to evaluate the impact of the supplementation on post weaning diets of the conventional source of zinc oxide (ZnO) and/or a potentiated source of zinc oxide (PZnO) and different (P) levels on productive performance, incidence of diarrhea, (Zn) and (Cu) fecal excretion. Eighty-four pigs weaned at 21 days of age were allocated in a randomized block design with four dietary treatments [T1: no inclusion of ZnO and regular P levels (0.440%; 0.420%; 0.400%; 0.380%); T2: inclusion of ZnO and regular P levels (0.440%; 0.420%; 0.400%; 0.380%); T3: ZnO and PZnO and 10% low P levels (0.396%; 0.379%; 0.360%; 0.340%); T4: inclusion of the PZnO and 10% low P levels (0.396%; 0.379%; 0.360%; 0.340%)], with seven replications and three pigs/pen. The nutritional program was: (pre-starter 1: d 21 to 28; pre-starter II: d 28 to 35; starter I: d 35 to 49; and starter II: d 49 to 63). The Tukey test was adopted to compare the means (SAS, 9.3). From d 1 to 14, T2 improved ADG (P < 0.05) and BW (P < 0.05) at d 14. From the period of d1 to d28, pigs fed with T2 diets showed higher ADG (P < 0.05), ADFI (P < 0.05) and, consequently, higher BW (P < 0.05) at d 28. From d 1 to 42, pigs fed with PZnO diet performed the highest ADFI (P < 0.05). Evaluating overall data of diarrhea, T2 reduced the incidence of diarrhea (P < 0.05). T4 reduced Zn and P fecal excretion during the period from d 7 to 28 (P < 0.05). Therefore, the use of ZnO and PZnO provide the same performance results of piglets on the period from d 1 to 42 after weaning. Furthermore, the inclusion of PZnO reduces the Zn and P fecal excretion.
