| Abstract | ||
| This experiment was conducted to investigate the comparison efficacy of a commercial probiotic containing Saccharomyces cerevisiae with a commercial acidifier on performance, morphology of intestine and intestinal bacterial count in commercial broilers. Current study was performed with 20 experimental units in completely randomized design manner with four treatments in four replicates having fifteen chicks in each replicate with mixed-sex Ross 308 chicks for 42 days of duration. The first treatment was the basal diet only and in second, third and fourth treatments, basal diet were implicated along with 0.1% of probiotic, 0.1% of Organic acids supplements and 0.05 + 0.05% of probiotic and Organic acids supplements, respectively. Results showed that at the end of the trial, using a suitable strain of Organic acids supplements along with probiotic improved body weight and feed conversion ratio. The minimal presence of coliforms and salmonella bacteria was found in treatment receiving combination of probiotic and Organic acids supplements, and the minimal count of E. Coli count was found in Organic acids supplements fed group. An increase in height of intestinal villus were found in chickens received probiotic and Organic acids supplements, and an increase in the number of goblet cells and crypt depth were observed in control and probiotic fed groups, respectively (P<0.05). In conclusion, the combination of probiotic and Organic acids supplements in broiler’s diet may improve performance and result to decrease in the presence of infectious intestine bacteria. | ||
