Further information
The effectiveness of the vaccine in providing passive immunity to young lambs and calves depends on these animals ingesting adequate amounts of colostrum on the first day of life.
Clinical trials have demonstrated that the presence of maternal antibodies, particularly against C. tetani, C. novyi type B, C. perfringens type A (calves only), C. chauvoei (lambs only) and C. perfringens type D may reduce the antibody response to vaccination in young lambs and calves. Therefore, to ensure an optimal response in young animals with high levels of MDA, the basic vaccination should be delayed until the levels wane, usually after about 8-12 weeks of age.
