The investigation of the effect of toxin binder and probiotic on performance of broiler chickens by multi- index decision management approach

This study was conducted to investigate the efficiency of dietary inclusion of ASRI1 and ASRI2 commercial toxin binders and probiotic on performance, immunity, and intestinal microbial population of broiler chickens fed with aflatoxin-contaminated diets. A total number of 420 1-d-old broiler chicks with initial weight of 42±3, were assigned to 7 treatments with 5 replications (n=12). Experimental treatments included 1) non-aflatoxin contaminated diets (NC), 2) aflatoxin-contaminated diet (PC), 3) PC diet containing probiotic, 4) PC diet containing ASRI1 toxin binder, 5) PC diet containing ASRI2 toxin binder, 6) PC diet containing probiotic+ASRI1 toxin binder, and 7) PC diet containing probiotic+ASRI2 toxin binder. Performance, absorption index, intestinal microbial population, immunity index and survivability percentage were recorded and used as indexes for the comparison of the treatments. Multi-index decision management method was used to select the best treatment and decision about probiotic and toxin binder use. Based on the scoring obtained by this method, treatments of 1, 7, 6, 5, 3, 4 and 2 obtained the scores of 0.6264, 0.55674, 0.5118, 0.4171, 0.22244 and 0.0221, respectively. Based on Multi-index decision management method method, weight gain and production index had most role and the best response was observed in broiler chicks fed with probiotic and toxin binder (ASRI2). Therefore, a combination of probiotic and toxin binder (ASRI2) is recommended as a strategy for improving productive and performance traits of broiler chicks infected with aflatoxin
