Why would the Nutrient Analysis change if the formula hasnt changed?
The ingredients used to make pet foods are derived from fresh and dried food ingredients. There are differences in these ingredients from one season to the next, one supplier to the next, and can even be slightly different from one lot to the next. This is a fact of life that dieticians, nutritionists, food companies, and pet food companies have dealt with for as long as balanced diets were considered important. It is this simple fact about variation in nutrient composition in ingredients which drives the differences between the GA and the actual NA. To compensate for the variation, we formulate to exceed the minimums by a reasonable amount and control the maximums to stay below the level of tolerance necessary to provide a food that truly meets the customer and their pets needs.
