Preventing Costly Leg Deformities in Poultry with CLA


Mark Cook, Michael Pariza, Daria Stransky

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a method of preventing the incidence of twisted or bowed skeletal problems in poultry by administering CLA.
OVERVIEWIt has been estimated that annual industry losses due to leg problems in broiler chickens can exceed $100 million. In the United States alone, skeletal defects cost turkey producers more than $30 million. Such birds are more likely to die before reaching market, or have their meat culled or downgraded. Toxins, chronic diseases and nutritional disorders like rickets are leading causes.

Conjugated linoleic acid (CLA) is a powerful natural food ingredient that promotes meat quality and animal health. Given to poultry, it also promises to reduce this major industry liability.
THE INVENTIONUW–Madison researchers have developed a method to prevent skeletal problems in poultry, especially twisted or bowed leg deformities.

As a food additive, enrichment or veterinary dose, a safe amount of CLA is administered. Differences in age, size and type of bird determine how much is required to be effective. Envisioned species include chicken, turkey, goose, emu, pheasant, ostrich, rhea and other ratites.
