This study evaluated the effect of a prebiotic (MOS) and of a probiotic (bacterial pool), acting as alternative additives instead of antibiotics, on the performance and on the intestinal morphology of broilers. In this experiment, 960 chicks were used on litter previously used. The birds were randomly assigned to four different treatments: Antibiotic; Prebiotic; Probiotic; and the control treatment, with eight repetitions for each treatment. For the whole breeding period (42 days) the alternative additives did not show any effect on the weight gain and feed intake. The feed conversion in the alternative additives groups was similar to that of the antibiotic group, however, it was not significantly different from that of the control group. It was not possible to observe any beneficial effect of the alternative additives, used in this essay, on the intestinal morphology of broilers.
