Because farm animals do not evolve, they are bred. We have directed their evolutionary paths for centuries, away from what it would do on it's own, towards creatures that produce more milk, more meat, or fattier meat.
From a calories-per-unit-of-labor standpoint, dogs and cats have now clearly eclipsed humanity, using their emotional intelligence to create a post-scarcity Marxian utopia where they can mostly do whatever they want all day while humans toil for them.
