1. A transgenic, non-human mammalian animal whose genome comprises:
- a stably integrated, recombinant nucleic acid encoding a polymeric immunoglobulin receptor (pIgR) protein operatively linked to a mammary specific promoter;
wherein a mammary gland of said transgenic, non-human mammalian animal over-expresses said pIgR protein as compared to expression of the pIgR protein in a mammary gland of a wild-type, non-human mammalian animal;
wherein said pIgR protein transports a polymeric immunoglobulin protein across the basolateral side of a mammary gland'"'"'s epithelial cell to the apical side of the mammary gland'"'"'s epithelial cell as compared to a different immunoglobulin protein located on the epithelial cell'"'"'s basolateral side.

Abstract
Methods and processes for raising the concentration of a first class of immunoglobulin relative to at least a second class of immunoglobulin in a compartment of the body of a non-human animal or the progeny thereof, as well as the animals produced by such methods and processes. Such methods and processes provide for the collection of antibodies produced by mucosal surfaces of the animal. Preferably, the production is in the mammary gland. Antibodies can be collected from the milk of the animal. Antibodies may be used for medical and/or nutritional purposes.
