A Comparative Study of the Effect of Non-Antibiotic Feed Additives on Experimental Colonization of Salmonella Enterica Serovar Enteridis and Intestinal Pathomorphology in Broiler Chickens

The objective of this study was to evaluate the effect eubiotics on intestinal morphology broilers. For purpose, 125 birds were divided into six groups with two replicates each (10 in replicate). Group A given a Basal diet. All except group challenged Salmonella enterica serovar Enteritidis. B provided basal diet, C fed Probiotic-added diet; D Prebiotics-based E essential oils plus and F organic acids Two separate experiments carried out for recovery, checking cecal tonsils conducting an pathomorphic evaluation. Villus length, villus width, surface area, crypt depth measured by micrometry. There overall improvement (p<0.05) morphometric parameters all treatment negative control group, which showed lowest height values. Maximum duodenum achieved E, diet containing oils, whereas maximum area index recorded D, prebiotics. ileum mucosa (treated prebiotics). It is concluded that there increase gut histology broilers non-antibiotic based feed.
