Evonik has launched a new standardized ileal digestibility (SID) database for swine feeds which – for the first time – provides SID values of all amino acid for weaners, as well as for grower pigs. The new information means that feeds formulated specifically for weaners will no longer need to be based on digestibility data from growers – which should more closely meet requi...
Formulating diets using SID values is a good approach to count how much of each AA could be potentially used by the pig. However, having separately SID values for weaned and grower pigs, is a step closer to accuracy.
