The study aims to check the impact of supplemented Lysozyme and Acidifiers on growth performance and immunity in broilers. For this purpose, 160 broiler chicks obtained from a local company’s hatchery, raised to the age of 42 days, and vaccinated against ND, IB, IBD, and H9 according to the commercially available vaccine schedule of that area. These chicks separated into four groups A, B, C, and D equally, each having two replicates (n=40). Group A will not receive any treatment and understood as the control group, group B treated with Lysozyme (lysozyme 50 %, 1ml/4 liter of drinking water), Group C treated with Acidifiers (combination of organic acids 1ml/4 liter of drinking water), and group D will be treated with Lysozyme (lysozyme 50 %, 1ml/4 liter of drinking water) and Acidifiers (combination of organic acids 1ml/4 liter of drinking water) in this group we were checked the combined effect of lysozyme and acidifiers. Starter feed offered from day 1 to the age of 21 days and finisher offered from 22 to the age of 42 days. Blood sampling done at ages 28 and 35 for antibody titers. The body weight of chicks was measured at age days 7, 14, 21, 28, 35 and 42 days. At end of the experiment recorded data of body weight gain, feed consumption, antibody titers, and hematological analysis statistically analyzed by using statistical techniques the variance technique under a completely Randomized Design, and mean values compared by using Tuckey’s test. The result of this experiment set a direction to the use of lysozyme and acidifiers at the commercial level in the field.
