  1. 1. Antimicrobial Activity of Peppermint Oil and Its Effect on Antibody Response Of Broilers to NDV Vaccine
  2. 2. Materials and Methods 100 day old broiler chicks were divided in to four groups (A, B, C and D) with 25 birds in each. Group ND Vaccination Peppermint Oil Treatment A √ √ B √ --- C --- √ D --- ---
  3. 3. Vaccination  On day one – NDV and IBV vaccine (Bivalent) was administered to each bird of group A and B using spray method.  On day 21 PFT (post first treatment) – Live attenuated NDV and IBV vaccine were administered to each bird of group A and B through drinking water.

  5. 5. Challenge Infection  At 35 days of age  Velogenic strain of the ND virus  0.2 ml  Intranasal  100 EID50.
  6. 6. Evaluation 1. Clinical signs 2. Symptoms, morbidity and mortality For 10 days post challenge infection. 3. Anti-ND HI antibody titer of all birds was monitored on days; 14 – 21 – 28 - 35
  7. 7. Results Treatment (Group of Broilers) n=25 Geometric mean titer of anti-NDV-HI *antibodies at different age (days) of broilers 14 21 28 35 A Vacc - Treat 6.1 6.4 7.2 7.5 B Vacc - Non treat 5.4 6.1 6.6 6.9 C Treat - - - - D Non - Non - - - -
  8. 8. Results  Essential oils did not show any effect on weight gain and feed conversion ratio of the treated broilers.  Droppings from Essential oils treated birds showed no urease producing bacteria while 100 percent droppings of the untreated birds showed urease producing bacteria.
