Effect of Aloe Vera (Aloe barbadensis) Supplementation on Immune Status, Haematological and Serum Biochemical Parameters in Quails

Objective: Aloevera is the medicinal plants found in tropical regionsof India and is commonly incorporated in mostofthe poultry herbal medicines like liver tonics, antistress, antioxidants, antitoxic and growth promoting preparations. Apart from these benefits, it is used for variousfunctions like antibacterial, antiseptic, anti inflammatory, nematocidal and immune modulatory properties. Besides, its usage for medicinal preparations,it can also be included in the poultry diet as feed additive to utilize their benefits to the maximum extent.Material method: This study was conducted on 30 quails to show the effect of Aloe veraon serum biochemical, haematological and immunological parameters.quails were randomly divided into 3 groups, each group consisting of ten birds. All the birds were fed according to requirements. The birds in control group (T1) were given no supplement where as in treatments ( T2), ( T3) birds were supplemented with Aloe vera leaf powder at 0.25, 0.5 % of feed respectively. blood samples were taken for measuring biochemical and hematological and immune status analysis.Result: Haemoglobin concentration, packed cell volume, total erythrocyte count and total leucocyte count, serum protein, albumin, globulin, albumin-globulin ratio, glucose, triglycerides were not affected by Aloe vera supplementation. Immune response as revealed by delayed type of hypersensitivity (measurement of skin thickness) and serum immunoglobulin were improved in the T3 group. It could be concluded that Aloe vera supplementation at 0.5 through feed improved immune status of quails without affecting haematological and serum biochemical parameters.
