Abstract: This study looked at how broilers immune parameters measurements were affected by humic substance supplementation. One hundred twenty-day-old broiler chicks were divided into four groups: the control group (T₁) was fed a standard diet prepared in accordance with the Bureau of Indian Standards (2007), while the three experimental groups were fed diets containing 0.02% humic substance (T₂), 0.04% humic substance (T₃), and 0.02% bacitracin methylene disalicylate (T₄). On the 42nd day of the trial, there was no discernible improvement in the immune response against Newcastle disease and infectious bursal disease, nor was there any significant difference in the immune organ weight between all the groups and the control.
