Why do most dairy farmers choose to feed their cows a non-grass-based diet?

Corn and grain causes the cows to produce more milk, but at a cost both in supplying the grain and in the cow’s overall health! Grain also puts stress on the cow’s whole rumination system, which is designed to eat pretty much 100% forage diet.  We hope many more farmers will get off the crazy cycle and take the time and effort to begin the journey of becoming 100% grass-fed dairy farms.
