The breeding goal for food production aims, irrespectively of the species, at: improving gross efficiency (amount of product divided by the amount of feed consumed) en reducing the cost price by: 1) improving productivity (higher yield and financial returns, 2) improving feed conversion (less feed per kg of product and less costs) and 3) improving reproduction, health and survival (less replacement animals needed and less costs). Increasing attention to improve welfare and to reduce environmental impact might be additional breeding goal traits.
