When milk prices drop, it’s natural for dairy farmers to want to reduce expenses. The focus is often placed on input costs like an ingredient in the ration. However, looking at the cost alone could be detrimental to dairy herds, especially during tough economic times.

“Cutting blindly to save pennies up front can cost dollars in the long run,” says Stu Rymph, Ph.D., dairy nutritionist with Purina Animal Nutrition. “Instead, it’s important for you and your nutritionist to work together to identify your herd’s goals and priorities, evaluate the ration and be practical with the budget.”


Every ingredient has a monetary cost, as well as a cost of missed opportunity. Evaluating impacts to milk production, milk quality and animal health can be a better way to gauge an ingredient’s value in the ration rather than focusing only on the direct per-cow expense.

“Remember, anything added over time was added for a reason and should have provided a positive return,” stresses Rymph. “However, situations change over time. Not every product provides the same return on investment as market conditions change, so it is important to evaluate their impact.”

Although it can be difficult to quantify some benefits, like animal health, looking at milk production and its relation to income over feed cost (IOFC) can help measure the ROI on different feed ingredients.

“It is also good to monitor treatment costs, inclusive of labor and medications, as well as vet bills to catch any health-related costs or benefits,” says Rymph.

He adds, “What you feed your herd ultimately fuels their milk production and impacts health. Take the time to review the ROI of your ration and work with your nutritionist to make smart feed decisions, benefiting your bottom-line.”
