What should buyers specify for poultry, broiler and layer feed additives?

State the bird category and production stage, base diet, intended technical function, inclusion route, expected feed-processing conditions and destination market. Broiler, layer and breeder programmes can require different nutrient contributions and use directions. Confirm additive authorisation, maximum or minimum levels where applicable, compatibility with medication or other additives, and homogeneity at the proposed dose. Performance language should reflect valid evidence and should not imply treatment of poultry disease.
