By-products are an excellent source of protein and other nutrients.
By-products can be more nutritious than meat alone.
“Healthy and appropriately-sourced animal by-products play an important role in complete and balanced pet foods as well as in human foods by allowing us to use, rather than waste, nutritious components of a whole food ingredient. By-products are an important component in feeding a growing populations of humans and pets alike.”
