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. In 2008, at the American Society for Animal Science (American Society of)
