BackgroundSpray dried plasma (SDP) is a protein rich product obtained from the industrial fractionation of blood from healthy animals.

Spray dried porcine plasma is a protein source used in pig feed that has many functional components that significantly improves pig performance [1,2]. At a manufacturing plant, plasma is separated from red blood cells by centrifugation, concentrated and subm ...
