Resumo: The use of probiotic in animal nutrition has been identified for reducing mortality resulting from intestinal colonization by pathogenic micro-organisms, improving the performance and characteristics of production, leaving no residue in meat. The experiment aimed to isolate, from faeces samples from swine in the suckling strains of lactobacilli in order to be identified as probiotics. 92 colonies were isolated, these pre-selected colonies were subjected to the catalase which 60 negatively. The 60 colonies were subjected to negative Gram stain were evaluated where their morphology. Of these, 16 had forms of bacilli. These isolates were compared for their ability to resist pH 3.0, to grow in the presence of bile salts, phenol, lysozyme, its ability to hydrophobicity and antagonistic. Isolates L03, L04, L08 and L15, identified in this study show better for probiotic use, according to show better performance on the acidic conditions, growing in the presence of bile salts and phenol, with high percentage of hydrophobicity and inhibiting Escherichia coli
