Abstract
Three feeding trials were conducted to evaluate the impact of dietary fortification of Chicory, Moringa Oleifera and Nettle leaves feed additives on performance, immune status, and gut health biomarker of broiler chicks. Experiment I was carried out using 180 one day old Cobb broiler chicks. The birds were randomly assigned into three different groups; each group was subdivided into three replicates (20 birds each). group I served as control fed the basal diets only. group II fed on basal diet+ 0.5% chicory leaves. group III fed on basal diet +1% chicory leaves. Experiment ll was assigned using 180 one day old Cobb broiler chicks which randomly divided into three different groups; each group was subdivided into three replicates (20 birds each). group I served as control, and fed the basal diet. Birds of group II were fed the basal diet +0.5% Moringa Oleifera leaves (MOLM). group III fed on basal diet +1% MOLM. Experiment III was assigned using 180 one day old Cobb broiler chicks which randomly divided into three different groups; each group was subdivided into three replicates (20 birds each). group I served as control, and fed the basal diet. Birds of group II were fed the basal diet +0.5% Nettle leaves. group III fed on basal diet +1% Nettle. During the entire growth out period, chicory, MOLM and Nettle leaves improve significantly in growth performance , dressing %, have antioxidant activity and decreasing cholesterol and triglycerides with no significant difference in kidney health indicator but chicory and Nettle have a hepato protictive effect also all treatments improved gut health by increasing relative mRNA expression of MUC2 and occludin and decrease relative mRNA expression of IL8 and TGFᵦ however, Chicory group showed a significant increase in cecal acetic acid and butyric acid while MOLM affect on total SCFA and Nettle had a significant increase in butyric acid in addition to Chicory, MOLM and nettle fortification decrease total enterobacteracae and increase lactobacilli in addition to MOLM significant decrease in clostridium count. In conclusion the broiler chickens respond positively to chicory, Moringa Oleifera and Nettle leaves and improved performance, gut health biomarkers and antioxidant activity.
