| Abstract |
The present study was conducted to evaluate the immune response of pregnant ewes to simultaneous vaccination with Pneumo-4 (IBR, PI-3, BVD and BRSV virus) and pneumobac (Mannheimia, haemolytica, p.trehalosi and p.multocida), in addition , to maternal immunity transferred through colostrum to their offspring. The immune response against these antigens was estimated serologically in pregnant ewes, colostrums and newly born lambs until four months of age. All vaccinated ewes either with single or simultaneous vaccination responded serologically well and exhibited significant increased in antibody titers as compared with titers of controls. Colostral antibody titers were positively associated with those of ewes at lambing and in the neonatal lambs. In conclusion pregnant ewes can be safely vaccinated through simultaneous vaccination with pneumo-4 and pneumobac vaccines to control viral and bacterial respiratory affection in newly born lambs.
