Protein Sources as Functional Ingredients in Pig Diets
CANADA - Remarks by Alfons Jansman, Wageningen University, Netherlands, during the swine breakout session at the 2016 World Nutrition Forum in Vancouver, Canada.Introduction
The increase in demand for protein sources for animal feeds, related to the increase in animal production worldwide and to the increase in competition of use for human food, puts emphasis on efficient use of available protein sources. First of all, protein sources for animal feeds are carriers of protein and (essential) amino acids and other nutrients for production animals. In addition, specific constituents of these ingredients and peptides released during the enzymatic digestion of constituent proteins in the digestive tract can exert other, non-strict nutritional effects on e.g. feed intake, nutrient digestion, intestinal microbiota, signaling of the immune system or, after absorption, on physiological and metabolic processes. We are only at the beginning of understanding these ‘functional’ effects of dietary protein sources, which could generate added value when included in animal feeds. The aim of the present paper is to provide a short overview and some examples on functional properties of dietary protein sources in diets for pigs.
