Although everyone pretty much agrees that goats do a good job of consuming just the right amount of loose minerals when they are available free choice, there are still a lot of people who don't think goats (or other animals) can selectively choose to consume plants that they need when they need them. The concept of "nutritional wisdom" is something that Dr. Fred Provenza wound up studying throughout his career at Utah State University. I've heard about Dr. Provenza's research for about as long as I've raised goats, so it was really interesting to be able to talk to him in this episode. While most people would look at goats eating urine-soaked rat houses or a cow eating a rabbit and assume that it had no clue what it was doing, Dr. Provenza asked why.
