Influence of Dietary Plasma Proteins on Supporting Animal Immunity Systems

Spray-dried plasma (SDP) or spray-dried serum (SDS) are ingredients that are collected and processed to preserve the functional characteristics of the proteins. Spray-dried plasma or serum is a diverse mixture of functional components consisting of immunoglobulins, albumin, fibrinogen, lipids, growth factors, biologically active peptides (defensins, transferrin), enzymes and other factors that have biological activity within the intestine independent of their nutritional value. Spray-dried plasma is primarily used as an ingredient blended into dry feed or milk replacers. Spray-dried serum is an ingredient used in colostrum supplements and/or other liquid feeding applications.
