That just means the inefficiency is in the feed used and the farming practices, not in the animal.

Not really: having an animal in between makes you waste a lot of energy (because the animal only spend a fraction of this energy to build muscles, and the rest is just burned away to sustain its metabolism).

You can take the problem the other way around: the limiting factor is land, and if you have 1 square kilometers of (somewhat fertile) land, you will feed many more humans if you grow potatoes, wheat or rice on the land than if you feed a cow on this land (whether you fees the cow directly with grass or grow corn or soy on it to feed your cows).
