Compare methionine sources by nutrient delivery
Bioavailability is part of comparing methionine sources. This post focuses on the amount of useful nutrient delivered and the basis of a feeding comparison, rather than treating a lower inclusion rate as an automatic sustainability gain.
Comparing methionine sources involves the amount included in the ration and the nutrient that becomes available to the animal. Those quantities should be considered together. The source's sustainability theme adds another question: how the comparison is assessed environmentally. A lower product inclusion rate alone does not establish a lower footprint or an equivalent production response.
