The effect of supplementation of oregano oil and probiotic on blood biochemicals and immune response of broiler chicken

Abstract

Objective: To evaluate the effect of oregano oil and probiotic on blood biochemicals and immune response of Broiler Chicken. Methods: The blood biochemical parameter was estimated by autoanalyzer using standard kit of AGD, biochemicals (P), Ltd., and Mumbai, India. Serum samples were used for Haemagglutination Inhibition (HI) test as per procedure of O.I.E (1992) to detect the antibody titer against New Castle Disease. Result: The Biochemical analysis showed that group T3 oregano essential oil + probiotic in basal feed of broiler higher protein concentration in blood serum, lower cholesterol, BUN value was significantly dropped than control in the treatment group. The values for haemagglutination inhibition test were highest for treatment (T3 group). Conclusion: From the result obtained, it was concluded that feeding of oregano essential oil and probiotic Saccharomyces cerevisiae exhibited beneficial effect on the growth performance of broiler chicken
