Infectious Bursal Disease is one of them. Huge economic losses in case of infectious bursal disease are due to immunosuppression and high mortality.
In Pakistan, commercially available vaccines are abruptly used to control different viral diseases but unfortunately failure of these products occur from time to time. Hence, current study was designed to determine the immunostimulatory effect of two commercially available products (Mentofin and ASI-MIRUS) against IBD vaccine.
A total 300 broiler chicks were taken, divided into six groups each having 50 birds and were replicated under controlled conditions. A, B and D groups were vaccinated with the IBD live virus vaccine. B and C groups were treated with Mentofin. D and E groups were treated with ASI-MIRUS while F group served negative control. To detect antibody titer against IBDV at every week (0-42 days of age), a commercial ELISA kit, IDEXX Flock Chek standard (IDEXX Corporation, Westbrook, ME, USA) was used. In order to analyze gross and microscopic changes in bursa, postmortem examination and histopathology of bursa was done.
The volatile oils in Mentofin and ASI-MIRUS have effective immunomodulatory effects on humoral immune response in broiler chicks. Eucalyptus and peppermint oils increase bursa to body weight (B/BW) ratio as compared to untreated birds. Results of present study indicated the highest antibody titer in group D supplemented with ASI-MIRUS and vaccinated as compared to group B supplemented with Mentofin and vaccinated. Significantly high bursa to body weight ratio also observed in vaccinated group D (ASI-MIRUS treated) comparing with other

vaccinated groups A and B. In Group B (Mentofin treated), bursal samples showed necrosis at medullary region of bursal follicle. Group D (ASI-MIRUS treated) showed the active follicle consist of lymphoid cells and shown no obvious histopathological lesion. So present study showed that ASI-MIRUS is reduced the severity of IBDV which has more beneficial effect on immune response against IBD vaccinated Broiler Chicken as compared to Mentofin.
