Separate nutrient efficiency from carbon accounting
Methionine, nitrogen excretion, and environmental footprint are discussed together in the source. This post explains the need to identify which outcome is measured before presenting a feeding strategy as a sustainability benefit.
A feeding strategy may be evaluated through milk production, nutrient use, nitrogen excretion, or environmental footprint. These measures describe different outcomes. The source brings them together in its discussion of methionine. Keeping the boundaries clear helps readers understand which benefit has been measured. Carbon-footprint claims also need the assumptions of the environmental assessment.
