The objective of this study was to evaluate the effect of supplementation with multiprobiotics, yeast probiotic and antibiotic (Colistin) in diets for castrated male piglets during the nursery phase (23 to 56 days of age) on performance, healthy and economics. A total of 528 piglets from two genetic lines, being 264 from line A, e 264 from line B, with average weight of 7,0 and 6,7 kg respectilly were distributed in a factorial design 2 x 4. 2 genetic lines ( A and B), 4 experimental diets (1- Control, 2 - Control + 200g of multiprobiotic e, 3 - Control+ 1000g of yeast probiotic e 4 - Control + Antibiotic - Colistin 250g ton/food). Performance was assessed through weight gain, feed intake and feed conversion. The healthy was evaluated by the occurrence of diarrhea, presence of Salmonella, and amount of E. coli colonies. In the end of the experimental period the economic costs were calculated. Supplementation in diet of castrated male piglets during nursery phase did not affect performance and occurrence of diarrhea, but there were difference between genetic lines for all values. The multiprobiotic treatment presented the best economic viability between those which use any kind of supplementation.
