Plasma proteins are rich in immune substances, including functional proteins such as albumin, nutrient-binding proteins and immunoglobulins, in which the content of immunoglobulin crude protein is more than 15.5%. Plasma protein powder also contains a large number of growth-promoting factors, interferon, hormones, lysorizyme and other immune substances.
Spray-dried plasma protein powder (Spray-Dried Porcine Plasma,SDPP) is a kind of feed material containing highly digestible proteins, amino acids and high concentrations of functional bioactive components (such as immunoglobulin, transferrin, growth factors, peptides) and other bioactive components. A large number of peer-reviewed papers mentioned that compared with other high-quality protein feed materials, weaned piglets were fed a diet containing spray-dried plasma protein powder, its growth rate, feed intake, feed conversion efficiency and survival rate and other production performance can be more beneficial improved.
