6 alternative feed ingredients with functional properties

摘要

The definition of a functional ingredient will vary between scientific disciplines, but for the purpose of this article, we define a functional ingredient as an ingredient that improves animal performance and well-being more than what can be explainedsolely by our understanding of nutrition.Spray-dried plasma (SDP) is such a functional protein source that has considerable peer-reviewed research describing its impact on immune response and barrier function when fed to animals. Other functional ingredients that affect intestinal health include probiot-ics, prebiotics, egg antibodies, plant extracts and yeast derivatives.
