Summary:The present invention relates to: a method for producing a serum including protective antibodies having mucosal immunity which can protect against infection by mucosa-related infectious pathogens, wherein the method comprises a step for administering mucosa-related infectious pathogens to an adult cow via a mucosal route to induce, from the adult cow, the production of the protective antibodies having mucosal immunity which can protect against infection by mucosa-related infectious pathogens; and a method for protecting or treating calves from infection by infectious pathogens, by administering the serum produced by the method to newborn or young calves. Infection of calves by mucosa-related infectious pathogens could be prevented and treated by the method according to the present invention. The method of the present invention can be used as an effective means to replace existing vaccines in young mammals or to prevent or treat the infection of mucosal-related (digestive, respiratory and genital) infectious pathogens that have not been resolved by the existing vaccines. 본 발명은 점막관련 전염성 병원체를 성체 소에 점막 경로를 통해 투여하여 성체 소로부터 점막관련 전염성 병원체의 감염을 방어할 수 있는 점막면역성이 있는 방어항체의 생산을 유도하는 단계를 포함하는, 점막관련 전염성 병원체의 감염을 방어할 수 있는 점막면역성이 있는 방어항체를 포함하는 혈청의 제조방법, 상기 방법에 의해 제조된 혈청을 신생(newborn) 또는 어린 송아지에 투여하여 전염성 병원체의 감염으로부터 어린 송아지를 예방 또는 치료하는 방법에 관한 것으로, 본 발명의 방법에 의해 어린 송아지는 점막관련 전염성 병원체의 감염으로부터 성공적으로 예방 및 치료될 수 있었다. 이러한 본 발명의 방법은 어린 포유동물에 있어서 기존의 백신을 대체하거나 또는 기존의 백신이 해결하지 못한 점막관련(소화기, 호흡기 및 생식기) 전염성 병원체의 감염을 예방 또는 치료하는데 효과적인 수단으로 사용될 수 있을 것이다.
