SUMMARY An experiment involving 225 unsexed Hubbard broiler chicks was conducted for 35 days to determine the effects of varying probiotic ad symbiotic preparations on their growth performance, carcass traits, intestinal bacteria count and blood parameters (5 treatments, 3 replicates with 15 chicks per replicate). The treatments were, the basal diet without additives (control, T1), the basal diet with addition of symbiotic preparation (250g/ton) lacto-Pro, (T2), Bacillus-fort, (T3), Balacto, (T4) and probiotic preparation 500g/ton Zado, (T5). The results revealed that: Different probiotic and symbiotic preparations (T2-5) significantly increased BWG more than 18% (2284.90 g vs1937.40 g.) as well as FI (3276.25g vs. 2833. 75) and improved FCR from 1.43 vs 1.46 in comparison to the control. The best value was for T4. No significant differences were observed among treatments on carcass traits or lymphoid organs. Treatments 2-5 decreased pathogenic bacteria (E.coli and Salmonella) and increased beneficial bacteria (Bacillus subtilis, and Lactobacillus)in the small intestine as compared with the control, T1. Plasma Total protein, and Albumin were significantly affected by dietary treatment. In conclusion, probiotic and symbiotic supplementation to broiler diets had beneficial positive effects on productive performance and microorganisms in the small intestine. | ||||
