Abstract: A study investigated the impact of phytase enzyme supplementation on antibody titters against Infectious bursal disease (IBD) and Newcastle disease (ND), along with lymphoid organ weight in 120 Cobb broilers over 42 days of age. The experiment included a control group (T1) with 0.45% available phosphorus and three low-phosphorus diets with added phytase: T2 with 0.35% available phosphorus and 0.01% Phytase 5,000 FTU, T3 with 0.30% available phosphorus and 0.02% Phytase 5,000 FTU and T4 with 0.25% available phosphorus and 0.03% Phytase 5,000 FTU. Results showed no significant differences (p>0.05) in antibody titters against IBD and ND, as well as lymphoid organ weight among the groups on the 42nd day. Therefore, phytase enzyme supplementation in low-phosphorus diets did not affect the immune response against IBD and ND, nor did it alter immune organ weights in the broilers.
