More milk and components from each kilogram of feed is the basis for the feed efficiency equation. In countries where production caps have not been set, this idea resonates well since maximized production most often translates to additional revenue for the dairy.

Since other feedstuffs are typically priced to reflect the corn and soybean market, the cost of almost all feed ingredients has increased. Since feed is the largest single cost in producing milk, most producers review their feeding program to see if there are ways to reduce these costs. Any changes made to rations should only occur after a thorough review of the feeding program and must take into account the impact a change could have on other aspects of the overall operation.
