Nutrient, Antibody Pellets for Improved Animal Growth


Mark Cook, Daria Stransky

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing animal feed particles that support healthy and efficient growth of body tissue.
OVERVIEWDisease-free animals grow faster and more efficiently convert feed into body tissue such as muscle. Preventing animals, especially those raised for meat and food, from contracting diseases is economically critical. Antibiotics can be used to keep animals healthy but may leave residues in food. Antibody powders are readily incorporated into feed but have been show to degrade during pellet-making and granulation processes.

Another feed immunization option should be pursued that promotes efficient tissue development and protects animals from growth-adverse diseases and antigens.
THE INVENTIONUW–Madison researchers have developed convenient animal feed particles with a nutritious inner core and surface coated with antibodies or other feed-converting compound like conjugated linoleic acid (CLA).

The particles are first made by forming an extruded nutrient core of proteins and carbohydrates. Egg-derived or other antibodies can be added to the core in the form of a powder or deposited externally, within a protective lipid layer or not. CLA, a fatty acid that improves feed conversion efficiency, can alternatively be provided on the outer surface. The pellets are consumed orally.
  • Animal feed and passive immunization development
  • Protection from diseases and endogenous gut peptides, which compromise growth
  • Improved feed conversion efficiency
  • Antibodies on pellet surface are not degraded by ingestion.
