There is certainly a book market for encyclopedias of domestic animal breeds, although I doubt there is one for a single book with ALL domesticated animals. I imagine people interested in dogs have no real interest in goats, and goat people might have no interest in pigeons, so on and so forth. It WOULD be a lot of work however, as it would require a ton of new illustrations and text, versus field guides and so forth on existing wild mammals and birds, where the illustrations and such already exist.
If they were going to do a "from scratch" project of that scale I personally would prefer Herps, but to be honest that is probably an even more expensive and laborious task.
