The present experiment was designed to study the effect of different organic acid salts, prebiotic, symbiotic and antibiotic growth promoter (AGP) on immune response in broilers. A total of 252-day-old Cobb broilers chicks were randomly assigned to 14 different groups. The group T1 broilers were fed standard broiler diet and T2, T3, T4, T5, T6 were supplemented with 2% sodium acetate, calcium sorbate, calcium propionate, sodium butyrate and sodium lactate, respectively. Groups T7, T8, T9, T10 and T11 were supplemented with 3% salts. Group T12 was having probiotic, T13 symbiotic, whereas T14 AGP. Broilers were vaccinated on 7th and 21st day of age with F₁ strain and Lasota strain of Newcastle disease vaccine. Humoral immunity towards Newcastle disease was measured on day 30th and 42nd by the haemagglutination inhibition test. Supplementation of organic acid salts improved the humoral immune response in terms of HI titre when compared with the control, although supplementation was more beneficial and was comparable with symbiotic as well as AGP on 30th day. On 42nd day, symbiotic was comparable with 3% calcium sorbate and revealed the highest antibody response to Newcastle disease vaccine followed by probiotic, 3% sodium butyrate and AGP supplemented groups. Supplementation of organic acids or symbiotic in the diet of broilers can be a better alternate to AGP.
