Problem statement: An experiment was conducted to study the effect of microbial phytase&#13; supplementation and citric acid on thyroid activity, relative weight of lymphoid organs and pH values&#13; of some GI-tract segments in broiler chickens fed corn-soybean meal based diets. Approach: The data&#13; was analyzed using a Randomized Complete Block Design (RCBD) with factorial arrangement of 3×3,&#13; three levels of citric acids (0, 3 and 6%) and three levels of phytase (0, 500 and 1000 IU kg&#8722;1). There&#13; were three replicates (with ten chicks in each replicate) for each treatment. A total of 270 Ross 308&#13; broiler chicks were used. Results: Addition of citric acid to diets caused significant decrease in pH&#13; values of crop, gizzard, duodenum, jejunum and ileum (p<0.05) and caused significant increase&#13; (p<0.01) in plasma triiodothyronine (T3) concentration, T3:T4 ratio and relative weight of bursa and&#13; thymus, but had no significant effect on thyroxin (T4) concentrations. Microbial phytase significantly&#13; increased relative weight of thymus (p<0.01), but had no significant effects on thyroid gland activity,&#13; relative weight of bursa and values of pH in different parts of the GI-tract. Conclusion: Broiler chicks&#13; fed on acidifiers diets had better immune response resistance that lead to immunological advances.&#13; Also, decreasing pH in GI-tract by CA caused a beneficial effect in the inhibition of intestinal bacteria&#13; competition
