The transfer of maternal antibodies to Friesian and buffalo calves born of dams vaccinated against rinderpest was through colostrum only. Colostral antibody titers at the time of parturition were higher than the serum titer. Two hours after suckling, a high level of rinderpest neutralizing antibodies was detected in the sera of newborn animals. The half-life of maternal antibodies in buffalo and Friesian calves was found to be approximately 33 and 29 days respectively. By the age of 7-8 months, 60 per cent of buffalo calves and 80 per cent of Friesian calves had no detectable levels of rinderpest neutralizing antibody.
母体抗体向接种了牛瘟疫苗的母畜所产弗里斯兰犊牛和水牛犊牛的传递仅通过初乳进行。分娩时初乳中的抗体滴度高于血清滴度。哺乳两小时后，在新生动物血清中检测到高水平的牛瘟中和抗体。发现水牛犊牛和弗里斯兰犊牛体内母体抗体的半衰期分别约为33天和29天。到7 - 8月龄时，60%的水牛犊牛和80%的弗里斯兰犊牛体内检测不到牛瘟中和抗体。
