Abstract

This exprement was conducted to compare the effects of antibiotic and some Iranian and similar imported probiotics on PERFORMANCE, economic indicators and intestine morphology of BROILERs.540 1-day old BROILERs were used in a completly randomized design with 6 treatments and 5 riplicates per treatment. Pedi-Guard and Lacto-Feed were used as Iranian and Bactocell and Primalac probiotics as imported products. Treatments were: 1) basal diet (control) and basal diet with: 2) antibiotic, 3) Bactocell probiotic, 4) Pedi-Guard probiotic, 5) Primalac probiotic and 6) Lacto-Feed probiotic. Orthogonal contrasts were used to compare the effect of probiotics versus control and antibiotic, IRANIAN PROBIOTICS versus imported products and single strain probiotics versus multi strains. Primalac decreased feed intake and body weight gain, while antibiotic and Bactocell increased the feed intake and body weight gain in the starter period (P<0.05). These changes did not change the feed conversion ratio. Economic indices, production efficiency factor and body weight did not show any significant differences. Antibiotic reduced villus height, surface area and the crypt depth and the Primalac showed an increase in villus height and surface area in the jejunum (P<0.05). Contrast of antibiotic versus probiotics resulted in improvement in PERFORMANCE, gross profit, as well as decrease in jejunum length, crypt depth, villus height, and surface area (P<0.05). Reduction in crypt depth in ileum was the only change caused by using IRANIAN PROBIOTICS versus imported products (P<0.05). As general conclusion, IRANIAN PROBIOTICS, imported probiotics and antibiotic were not different from control group when judge based on PERFORMANCE and economic indexes.
