Abstract:
In current experiment, a total of 180 day-old unsexed Ross 308 broiler chicks were randomly allocated into three treatments and four replications of fifteen chicks each, in a completely randomized experimental design manner. Diets prepared without additive as Control (group1); 0.1% probiotic (group2) and 0.1% AGP (group 3). Results showed that addition of AGP and probiotic could significantly decrease the population of coliforms, salmonella and E.coli in broilers intestine and villus height (μm) and Villus height to crypt depth ratio was increased in treatment having probiotic containing Saccharomyces cerevisiae, whereas, the number of goblet cells in each 100 μm of villus height and also crypt depth ratio was significantly decreased in probiotic and AGP fed groups. It can be concluded that dietary probiotic could be positive replacer to antibiotic growth promoters, when included in to the basal diet of the current experiment.
