Garlic was used for the medicinal purposes and as a health supplement by the ancient Egyptians. It is a natural feed additive and is antimicrobial, immune stimulator, antiviral, antifungal, anti-parasitic, antithrombotic, antioxidant, anti-cancerous, and vasodilator activities. Previous studies indicate that it has beneficial effects on the immune system and is a best immune stimulator then the other herbal plants and medicines. Therefore, the present study was designed to estimate the immunomodulatory effect of garlic to commercially available IBD vaccine in enhancing the immune system. Total N=99 day old broiler chicks were purchased and kept in the experimental shed of CVAS Jhang. Birds were divided into three groups A, B, C and group B and C were further divided into three subgroups (B1, B2, B3 and C1, C2, C3). Group A was treated as control group and was administered with commercially available IBD and ND vaccine and routine diet while group B was administered with garlic at the rate of 4%, 5%, and 7% along with vaccine to see the impact of different levels of garlic (Allium sativum) on the immune system and to see the toxic effect (if any) of high dose of garlic. Group C was only administered with garlic in fee Summary 44 at the same rate as to group B. At the end of study birds were slaughtered to check the effects of garlic administration. Positive effect of garlic has been reported by many studies. Garlic is a medicinal herb used for the prevention and treatment of many diseases, because of having antiviral, antibacterial and antifungal activities. Also act as a good growth promoting agent and have beneficial effects on the immune system. Results of the study indicate that administration of garlic powder in different doses alone and combined with commercial IBD vaccine have good effects on the growth, blood parameters and the immune system of the broiler birds.

A number of feed additives including antibiotics have been extensively used in
poultry diets for the purpose of weight gain to improve feed efficiency and growth rate.
However, use of antibiotics has restricted due to the bacterial resistance and the issue of
residues which make the chicken meat harmful for human consumption. So the medicinal
plants are gaining interest as alternative feed strategies now a day because of their low cost,
easy availability and presence of no residues. Garlic was used for the medicinal purposes and
as a health supplement by the ancient Egyptians. It is a natural feed additive and is

antioxidant, anti-cancerous, and vasodilator activities. Previous studies indicate that it has

Therefore, the present study was designed to estimate the immunomodulatory effect
