How should cattle and calf feed additive specifications account for the feeding system?

Identify dairy or beef use, age and production stage, forage and concentrate context, delivery method and expected daily intake. Calf milk-replacer use is not equivalent to inclusion in adult ruminant feed. Technical review should cover ingredient form, rumen behaviour where relevant, mixing, stability and any species restrictions. Directions should be expressed so the final feed or daily ration remains within authorised conditions, with local nutrition and regulatory review before commercial use.
