Zusammenfassung:In order to study the pro-nutrients effects of probiotic, prebiotic and antibiotic on the performance and height of intestinal villi of weaned pigs at the age of 21 days. An assay completely randomized block design experiment was carried out during 42 days to compare four treatments: reference (control) - reference ration (without pronutrient); antibiotic - reference ration + 0.01 % of antibiotic (Tylosin); - reference + probiotic (Bacillus subtillis) and reference + prebiotic (mananoligosaccharides). In the experiment sixty four weaned pigs with the initial weight of 7.85 + 1.10 Kg were allotted in 16 pens, each one with four pigs on the initial period (1-21 days) and three on the final period (22-42 days) and four replications per treatment. At 42th day of experimental period, one animal of each pen was slaughtered to collect the content of the small intestine for evaluation of the intestinal villi height. No had differences (p>0.05) between treatments. The daily weight gain of initial period were 0.221, 0.233, 0.252 y 0.234 kg for control diet, antibiotics, probiotic and prebiotics diets. The daily weight gain at the final period were 0.452, 0.408, 0.447 y 0.404 kg respectively. Had difference of the intestinal vilosity height (p
