Early in my career, I had a feed store manager tell me, “Only the rich can afford cheap feed.” While he was partially correct, feeding dairy cows does allow us the opportunity to feed a variety of byproducts, based upon their nutrient value. There are a variety of software options that can describe the relative value of byproducts compared to more traditional feedstuffs, such as alfalfa hay, corn silage, corn and soybean meal.
