The use of feed ingredients in pig diets contributing to more circular food production: Literature study

This report reviews literature on the consequences of increasing the use of circular ingredients in pig diets to enhance the circularity of food production systems. A cluster of feed ingredients was selected and reviewed based on two scenarios, the first aiming to reduce the use of cereals in diets for pigs, the second aiming to decrease the use of protein sources from outside the EU, e.g. soybean meal, in pig diets. The effects of the use of these “circular” ingredients has been described considering their nutritional characteristics and effects on growth performance and carcass quality, as well as their potential effects on health and welfare of pigs.
