Nutrients to the food
In this case, the total corn amount may be a significant amount of the total food dry matter, but when presented as individual types, each type appears lower on the ingredient list. Although a food ingredient may be listed first, if that ingredient is 75% moisture, it will contribute a much smaller percentage of total nutrients to the food dry matter. Ingredients are listed in descending order of weight, on an as-fed basis, in the food. Canned food analyses can be converted to a dry-matter basis by simply multiplying pet food storage container by 4 because most canned foods contain ~75% water. However, comparisons across different food types should be made on a dry-matter or caloric basis. Direct product comparisons made between like products are generally valid. Consequently, whenever possible, the manufacturers average nutrient profile should be used to evaluate a food.
