Compared to just eating the grains ourselves. For cattle, it takes 100 calories of grains to produce 10 calories of beef.

  I think it's important to point out though that cattle can digest and "convert" a significantly wider variety of plant sources into meat. Our bodies simply can't digest a lot of what they can.

    Sure... but it's also important to point out that while cattle "should" eat grass and can eat silage... 78% of beef in America comes from feedlot cattle[1]. On feedlots, the cattle are fed grains, not grass/silage... grains that we humans can easily eat like soy, corn, and barley [2]. 1. https://www.huffingtonpost.com/nil-zacharias/its-time-to-end-factory-f_b_1018840.html https://www.huffingtonpost.com/nil-zacharias/its-time-to-end... 2. http://www.goodfoodworld.com/2012/01/grass-fed-vs-feedlot-beef-whats-the-difference/ http://www.goodfoodworld.com/2012/01/grass-fed-vs-feedlot-be...

      None of those cows are raised on feedlots. Feedlots are used to fatten and "finish" the beef. Most all cattle start their life being grass fed.
