Abstract

This study was conducted on sixty, one-day-old broiler chicks for five weeks to examine the effect of onion (Allium cepa) and sweat basil (Ocimum basilicum) supplementation on non-vaccinated and vaccinated broiler chickens̓ growth performance, biochemical parameters, antioxidant status as well as immunological studies. The chicks were divided into six equal groups, as follows: GI: basal diet free from additives, G II:  supplied with onion powder in dose 10g/kg diet from one day to 5 weeks without vaccination, G III: supplied with basil powder in dose 10g/kg diet from one day to 5 weeks old without vaccination and G IV: vaccinated and received basal diet only. Group V: group vaccinated with addition of onion powder in dose of 10g/ kg diet. Group VI: group vaccinated and supplied with basil powder in dose of 10g/kg diet. Our findings revealed that the activities of ALT, AST, GGT, globulin, malondialdehyde, IgM, and IgG increased significantly in the vaccinated group in comparison to compare the control one. However, the levels of creatinine, uric acid, GSH, and SOD didn’t alter significantly. On the other hand, the onion vaccinated group revealed significant improvement in the liver enzymes, MDA, antioxidants, and IgG levels. while the basil supplementation in the vaccinated group didn’t show significant improvement. It is possible to conclude that using onion powder in diet of vaccinated chickens improve the liver function, immunity, and antioxidant status and while the basil powder didn’t show significant improvement.
