Zeitsman presents some solid theories, and many of his ideas work quite well. However, there are certain aspects of his approach that simply don't make economic sense. He has a particular disdain for the stud industry and doesn't believe in measuring economic traits beyond pounds per acre. While that metric is valuable, it only works if your product is marketable. The breeds he promotes, unfortunately, aren't marketable to about 95% of feedlots, or they are penalized by more than 25% when sold. Additionally, his preference for small-framed cows results in weaning weights around 300 pounds, which is too light for our larger feedlots, as they struggle to put enough frame on those animals.
