Abstract: A recombinant fusion interferon for animals. The recombinant fusion interferon comprises an animal interferon and a Fc region of an animal immunoglobulin G (IgG). The animal interferon and the Fc region of the animal immunoglobulin G can be further joined by a linker. A polynucleotide that encodes the recombinant fusion interferon for animals, a method for producing the recombinant fusion interferon, and the use of the recombinant fusion interferon.

Abstract: The present invention relates to a recombinant fusion interferon for animals, a pharmaceutical composition thereof, and the use of the recombinant fusion interferon. The recombinant fusion interferon is represented by formula (I) or formula (II), (Porcine interferon)-(Linker)n-(Porcine immunoglobulin Fc fragment) ??(I) (Porcine immunoglobulin Fc fragment)-(Linker)n-(Porcine Interferon) ??(II) wherein n is 0 or a positive integer between 1 to 10, the recombinant fusion IFN specifically binds an antibody that specifically binds porcine interferon and an antibody that specifically binds porcine immunoglobulin Fc fragment.
