Considerations on feeding pigs with by-products – the Danish Experience

Abstract

In Denmark, by-products have been used for years with positive outcome. Demand is increasing for by-products for use in feed for livestock. In order to ensure that productivity does not drop significantly when switching to feed containing by-products, a risk analysis should be completed. In Denmark, years of experience, a multitude of nutrient analyses and feeding trials constitute the basis of recommendations for the use of by-products in feed.
