How are nutrients such as protein typically listed on a feed tag?

Nutrients such as protein are typically listed on a feed tag as a percentage by weight of the total content of the bag. This is a standard practice in the feed industry, allowing consumers to easily assess the nutritional value of the feed being purchased. The percentage reflects the amount of protein in relation to the total weight of the feed, providing a clear and direct way to understand the nutrient composition.

For example, if a feed tag states that the protein content is 20%, it means that 20% of the feed's total weight is comprised of protein. This method of measurement helps ensure consistency and clarity for both producers and consumers in terms of evaluating and comparing feed options. Other methods of expressing nutrient content, such as by volume or caloric content, are not standard for protein on feed tags and may lead to confusion rather than the straightforward understanding that weight percentages provide.
