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).
That's because we human cannot digest grass due to the lack of the proper mictobiote, but most cows in the modern world aren't fed with grass anymore but instead with soy, corn or other kind of high-nutrients food (for which we human are totally equiped to eat).
