The problem is that those pigs and chimps that try to interbreed and fail would be wasting time and resources and end up falling behind in fecundity to their "breed true" cousins. Evolution would disfavor such behaviors as they would represent a vanishingly small percentage of the their respective gene pools.

In this case, they're not really wasting resources as they would have been having non-reproductive sex anyway.
