Method for producing yolk antibody for prevention or treatment of pig digestive system diseases, yolk antibody produced based on it and use thereof

The present invention relates to the use of pig digestive system disease pathogenic bacteria or viral antigens to produce heteroantibody, a complex of the above antigens and heteroantibody are inoculated into laying chickens, thereby producing yolk antibody for prevention or treatment of pig digestive system diseases, yolk antibody produced based on it and use thereof. According to the invention,by adopting the method for producing yolk antibody for prevention or treatment of pig digestive system diseases, a complex of antigens and heteroantibody are inoculated into laying chickens, and egg yolk antibodies are produced in large quantities. The egg yolk antibodies produced therefrom have high specificity and binding to pathogenic bacteria or viruses of pig digestive system diseases, and effectively inhibit the growth of the above bacteria and viruses. Thus, pig digestive system diseases can be prevented or treated. 本发明涉及利用猪消化系统疾病致病菌或病毒抗原制造异种抗体，然后将结合了上述抗原及异种抗体的复合体接种到产卵鸡，由此制造卵黄抗体的猪消化系统疾病的预防或治疗用卵黄抗体的制造方法以及基于此而制造的
