Nutrition programs rarely fail through one dramatic mistake. More often, they drift. An ingredient specification is relaxed, an additive is introduced, nutrient margins are increased, and a processing adjustment becomes permanent. Each decision appears reasonable. Two years later, the company has a more expensive program that nobody would have designed deliberately from the beginning.
I have entered reviews where management expected to find one obvious nutritional error. Usually, there were none. The problem was a collection of individually small decisions made by nutrition, procurement, feed manufacturing, veterinary and production teams. And, because each department could defend its own decision, the complete program had never been challenged.
