Abstract

This study was conducted to determine the effect of dietary inclusion of essential oils via the drinking water as feed additive with and without probiotics on the immune response of broilers as measured by the antibody titers through Hemagglutination-Hemagglutinin Inhibition test. Total of two hundred forty (240) day-old Cobb broilers of mixed sexes were used. The population was divided into four treatment groups with 60 birds each. Each treatment was replicated six times with ten chicks per replicate. At least one ml of blood was collected via the wing vein from six broilers in each treatment group at day 35 of the broilers? age. Antibody titers from the broilers used in the study had no significant statistical differences among treatments. It could be concluded that essential oils used were not effective in raising the antibody titers of the broiler chickens against New Castle disease virus. Furthermore the use of essential oil and probiotic as feed additive in broiler chickens could still serve as an alternative replacement for antibiotic growth promotants used in the poultry industry.
