Abstract: This study was conducted to evaluate the effects of dairy waste supplement, Galipro probiotic, TechnoMos prebiotic in the diet on growth performance, immune response, microbial flora and intestinal morphometry in broiler chickens. This study was conducted in completely randomized design with 8 treatments and 5 replications. A total number of 1200 male broiler chickens (Ross 308) with similar body weight (42.0±1.0 g) were used. Diets contained Galipro probiotic, TechnoMos prebiotic and Dairy Waste (DW) supplement in the different level (2.5, 5, 7.5 and 10 kg ton–1). In this study, some parameters including growth performance, cellular and humoral immunities, cecal microbial population and intestinal morphology in broiler chicks were investigated. Results showed that birds in synbiotic group consumed more feed intake in comparison to other groups in finisher period (p<0.05). Body Weight Gain (BWG) and Feed Conversion Ratio (FCR) were not influenced by experimental treatments in starter and grower periods (p>0.05) while BWG and FCR were significantly higher and lower in 7.5 and 10% DW in comparison to control group in finisher period (p<0.05). The obtained results showed that levels of Immunoglobulin (IgG), Immunoglobulin (IgM), Immunoglobulin (IgT), intestinal villus height and thickness and becterial population of beneficial bacteria in the both periods were significantly higher in broiler chicks fed the 5, 7.5 and 10% DW+synbiotic in comparison to control group (p<0.05). In conclusion, the use of higher levels of DW (7.5 and 10%) and synbiotic in broiler chicks diets could be advised to improve immune system and growth performance that act by modulation in intestinal morphology and beneficial microbial population.
