摘要: In the Experiment 1, 50 pigs weaned at 21 days were fed with either of five diets: T1 - basal diet; T2 diet + antibiotic; T3 probiotic; T4 prebiotic; T5 simbiotic. The variables studied body weight, feed intake and conversion in Phase 1 (21 to 43 days), 2 (44 57 3 (58 70 days) Total days). During performance experiment, a fecal survey score was conducted verify diarrhea incidence. 2, 44 same diets 1. Pigs slaughtered three differents ages (at weaning, seven 14 after weaning). A segment small intestine collected for analisys total coliformes. results showed that best obtained utilization prebiotic There not differences relation incidence among treatments studied. addition probiotic and/or prevented increase colonization by pathogenic bacterias from weaning.
