For sure! And if you’re experimenting at home with such ingredients, you can definitely get away with including some of these ingredients in higher amounts, and seeing what happens! If you’re having several hundred thousand company dollars pass through your hands each week in the form of feed formulations though, nutritionists tend to try to be safe rather than sorry. Plus, these are all byproducts and byproducts, while often very cost-efficient, can have a high degree of nutritional variability, even within the same load. Maybe x amount got cooked too much and lost this percent of its nutritional quality and y amount wasn’t cooked long enough and isn’t as bioavailable. That’s why most byproducts are kept at fairly low inclusion levels.
