The invention is a method of producing all-pupa powder containing lactoferrin and its peptide, adopting bacilliform viruses as carrier, and using silkworm pupas as host to produce the gene engineering product with the bioactivity similar to that of the natural lactoferrin and the corresponding peptide. The producing and using course is safe and has no latent danger to human beings and animals and the environment. The all-pupa powder acting as feed additive can supplement feed proteins and simultaneously play a role in sterilizing and resisting viruses, and enhancing self-immunity of animals, and can effectively prevent and cure the diarrhea of weaner piglets, thus producing a high-quality animal product without residual antibiotics. 本发明的含乳铁蛋白及其肽的全蚕蛹粉的生产方法是采用杆状病毒为载体，以家蚕蚕蛹为宿主生产与天然乳铁蛋白及其肽生物学活性相似的基因工程产品的。其生产、使用过程安全，不存在对人畜和环境的潜在危险。将本发明生产的全蚕蛹粉用作饲料添加剂，在补充饲料蛋白的同时起到杀菌抗病毒、提高动物自身的免疫力的作用，可有效地防治断乳仔猪的腹泻，以生产出无抗生素残留的高品质畜产品。
