In the present study immunomodulatory effect of Mentofin® on antibody response of broilers to Newcastle Disease virus vaccine was evaluated. For this purpose one hundred one day old broilers were divided in to four groups (A, B, C and D) each containing 25 birds. Each bird of group A and B was vaccinated against ND and each bird of group A and C was treated with Mentofin. Anti-ND-HI antibody titer of each bird of each group was monitored on 14, 21, 28 and 35 days of age. Mentofin® treated broilers showed higher consistent antibody (anti-NDV HI antibody titer) response as compared to untreated broilers. These birds when given challenge infection of velogenic ND virus on 35 days of age showed same protection as that of untreated vaccinated birds. However non vaccinated broilers treated with Mentofin showed higher protection as compared to that of in non treated unvaccinated birds. Weight gain in Mentofin® treated broilers was same as that of non-treated birds. Similarly, there was no effect of the Mentofin on FCR. Droppings from Mentofin treated birds showed no urease producing bacteria while 100% droppings of the herbal untreated birds showed urease producing bacteria. Mentofin at 1% concentration in nutrient broth inactivated the proteus species while its 0.0001 % concentration inactivated the bacteria in urea broth. In in vitro studies, 0.5 % concentration of Mentofin inactivated the lentogenic strain of ND Virus within 15 minutes at interaction temperature of 37 0C. The results can be used to formulate the vaccination policy along with herbal based immunostimulatant such as Mentofin®.Item type | Current location | Collection | Call number | Status | Date due | Barcode | Item holds |

Immunostimulants such as Mentofin® are commonly used to enhance the immune response of birds to vaccines.

The results can be used to formulate the vaccination policy along with herbal based immunostimulatant such as Mentofin®.
