An experiment was carried out to evaluate the impact of flaxseed powder supplementation on the serum lipid profile and immune status of broiler chickens. A total of 150 Cobb chicks were assigned to five dietary treatment groups and reared until 42 days of age. The treatments included: T₁-control group (basal diet formulated as per BIS, 2007), T₂-basal diet with 5% flaxseed powder, T₃-basal diet with 7% flaxseed powder, T₄-basal diet with 10% flaxseed powder, and T₅-basal diet with 12% flaxseed powder. The findings indicated that the inclusion of flaxseed powder had no statistically significant effect (p>0.05) on the immune response to Newcastle Disease (ND) and Infectious Bursal Disease (IBD) when compared to the control group. Additionally, there were no significant differences (p>0.05) in the relative weights of immune organs across all treatment groups at the conclusion of the trial (42 days). It was therefore concluded that dietary flaxseed powder, even up to a 12% inclusion level, did not influence the immune status of broilers under the conditions of this study.
