Colostrum from ewes that had been repeatedly exposed to cestode infection, whether or not their immunity was boosted by vaccination with Taenia ovis, transferred a strong immunity to the lambs. Susceptible ewes, not recently exposed to tapeworm eggs, gave no protection to their lambs via the colostrum. There was no evidence that colostrum-deprived lambs were more susceptible to infection with T ovis than lambs that received colostrum from non-immune ewes. Colostrum from naturally immune vaccinated ewes gave good protection to lambs for up to six weeks but thereafter the effect was variable. The immunity that developed in susceptible ewes after vaccination with activated embryos was not passed on to the lambs via the colostrum.
反复接触绦虫感染的母羊所产初乳，无论其免疫力是否通过接种绵羊带绦虫疫苗得到增强，均可将强大的免疫力传递给羔羊。近期未接触过绦虫卵的易感母羊，无法通过初乳为其羔羊提供保护。没有证据表明，与从非免疫母羊获得初乳的羔羊相比，初乳缺乏的羔羊更容易感染绵羊带绦虫。自然免疫的接种疫苗母羊所产初乳，可在长达六周的时间内为羔羊提供良好保护，但此后效果不一。接种活化胚胎疫苗后，易感母羊产生的免疫力不会通过初乳传递给羔羊。
