MMMmmm... there is something odd here. It would cost a fortune to house all of those cattle in confinement.Also nice to hear, but according to this, 99% of meat in the USA is factory farmed

I suspect that they are figuring the numbers of animals in those figures. One confined chicken to one free cow equals a 50% confinement rate, done that way.
