Likely as goats are far easier to keep, own, feed and tend to than cows - especially for the poor. Goats can be kept on any land, can get pregnant/give birth multiple times per year (and therefore provide milk) and have a long weening time when they will give milk. I'd imagine the availability of goats was likely the defining factor in your evidence -but again just an assumption.
