Method of Using Anti-Phospholipase A2 Antibodies to Enhance Animal Growth or Improve Feed Efficiency


Mark Cook

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a method for enhancing animal growth or feeding efficiency.
OVERVIEWEnhanced animal growth can reduce the cost of feeding animals produced for human consumption, like poultry. Currently, there are several techniques for maintaining the health and increasing the growth of animals. One of these methods involves adding ionophore antibiotics to animal feed. However, this is not desirable for animals raised as foods because antibiotic residues may remain in the food.
THE INVENTIONA UW-Madison researcher has developed a method of using antibodies against phospholipase A2 to limit the production of lipid metabolites, such as prostaglandin and leukotrien. This reduces stimulation of intestinal smooth muscle, leading to more efficient food conversion and increased body growth.
  • Meat animal production
  • Enhances animal growth and improves feeding efficiency, without deleterious effects
  • Reduces the high cost of feeding food-producing animals; this is a significant savings since seven billion broilers are raised annually in the U.S.
  • Brings the broiler to market maturity faster
  • Potentially reduces or eliminates the need for standard nonsteroidal anti-inflammatory drugs (which cause ulcerogenic side effects)
