| This trial was conducted to evaluate the effects of oregano essential oil supplementation at concentration of 50 mL/1000L of drinking water on immune response in broiler chickens and performance. 390 day old Rose chickens were housed together in six experimental boxes 65 chickens for each box, including non-vaccinated group and non-vaccinated oregano treated group. Group A: vaccinated with (la Sota vaccine via eye drop) at 5 days, 15 days, 28-day old adding oregano essential oil in drinking water one-day post vaccination. Group B: vaccinated with (la Sota vaccine via eye drop) at 5 days, 15 days, 28-dayold only without oregano essential oil. Group C: vaccinated with (inactivated ND vaccine) at 5-day old via S/c injection one dose adding oregano essential oil in drinking water one-day post vaccination for three days. Group D vaccinated with (inactivated ND vaccine) at 5-day old via S/c injection one dose only without oregano essential oil. Group E: Non vaccinated as control group. The effect of oregano essential oil in drinking water combined with two forms of live and killed Newcastle disease virus vaccines on the immune responses and serum proteins was investigated in broiler chickens. Results showed a significant effect oregano on immune response of chicks in group D and C which were vaccinated with killed vaccine at 23 and 33 day-old and recorded a peak at 38 day with a significant difference (p < 0.05) in vaccinated and non-vaccinated group as well as in 38 day-old for group C significantly increased (p < 0.05) compared with other groups regarding the oregano effects on immune response of groups A using live attenuated LaSota vaccine as booster dose was significantly increased compared with group B and control groups. In addition, increase in the serum protein significant differences (p > 0.05) of the vaccinated broiler chicks and serum globulin showed quantitative increase in the vaccinated broiler chicks compared with non-vaccinated groups in the other hand the result showed the effect of oregano non-significant difference (p > 0.05) had no beneficial effect on growth performance. | ||
