Descrição: dc.descriptionThe effect of probiotic (Bacillus amyloliquefaciens) and organic acids (lactic, acetic and butyric acid), isolated or combined, in an attempt to replace the antibiotics (avilamycin+sodium monensin) on intestinal anaerobic bacteria, allometric growth of digestive organs, intestinal morphometric and performance of broilers challenged by Eimeria (acervulina, maxima and tenella) were studied in a 1 to 21-d experiment. A total of 900 male Cobb chicks were distributed in a completely randomized design in a 2 x 2 + 1 factorial arrangement, presence or absence of probiotic and organic acids more a positive control with antibiotics, with six replicates. The probiotic promoted some changes on total anaerobic microorganisms throughout the small intestine in both periods (p<0.02), whereas the antibiotics decreased this counting only until 14 days (p<0.04). Antibiotics increased liver weight at 14 days (p<0.01) and reduced the relative weight of the pro-ventricle, gizzard and all segments of the small intestine at 21 days (p<0.01). At 14 days, the alternative additives reduced the villus height and crypt depth (p<0.05), whereas the probiotic increased the width of the villus base (p<0.01). Antibiotics reduced the crypt depth and width of the villi in the small intestine in both periods (p<0.05). Although some changes in the intestinal microbiota and morphology, the alternative additives, isolated or combined, did not change the birds’ performance (p>0.05), only the antibiotics provided better results on BW gain and feed: gain in 1 to 14 and 1 to 21 d-old (p<0.05) of broilers challenged with Eimeria spp.-
