Diets for dairy cows and heifers need to supply nutrients, not specific ingredients, to support growth, milk production, and the needs of the animals themselves, known as maintenance by nutritionists.  With corn and soybean meal prices increasing tremendously, substitutions in diets for these ingredients may be financially beneficial.  Elanco Animal Health weekly calculates the nutritive value of various by-products, grains, and forages.  To complete these calculations, they use current market prices sourced from USDA data and then use a computer program to predict a nutritive value or price for selected by-products, grains, and forages.  The difference between the market price and predicted price can be a starting point to determine if a particular ingredient is a good buy to consider along with the advice of your nutritionist.  Those ingredients with a positive difference are good buys and those with negative values are overvalued.
