Replacement of soybean meal in compound feed by European protein sources : effects on carbon footprint

Er is een studie uitgevoerd naar de duurzaamheid van enkele Europese eiwitbronnen ter vervanging van sojaschroot van Zuid-Amerikaanse herkomst. Op basis van data uit de literatuur en de systematiek van het programma FeedPrint zijn de nutritionele waarde en de carbon footprint (CFP) van deze eiwitbronnen vastgesteld. Deze eiwitbronnen zijn ingerekend in een startvoer voor vleesvarkens, zonder dat de nutritionele waarde van het startvoer veranderde. Vervolgens is de CFP van het startvoer vastgesteld. De resultaten en conclusies worden in dit rapport besproken.The overall aim was to investigate if soybean products from South American can be replaced by protein sources produced in Europe in a sustainable way. Based on data from literature, and based on the systematics of the FeedPrint programme, the nutritional value and the carbon footprint (CFP) of these protein sources is determined. These protein sources are used in feed optimizations of a starter diet for pigs, thereby maintaining the nutritional value of the diet. Subsequently, the CFP of the grower diet is calculated. The results and conclusions will be discussed in this report.
