Better Meat from Animals Fed with Conjugated Linoleic Acid (CLA)

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing animal diets with conjugated linoleic acid that promote increased fat firmness, shelf life and meat quality.
OVERVIEWAmericans’ growing preference for lower calorie fats has resulted in restaurant greases and genetically altered crops that are increasingly unsaturated. These oils and spent greases often are used to feed meat animals, including pigs.

Animals that consume more unsaturated oils develop softer fat and tissue, however, and in turn produce less valuable slicing meats, like bacon. Additionally, meat processed from such animals is more susceptible to rancid odors and flavors when exposed to air. Recognizing the trend in animal diets, it would be desirable to create an enrichment that counteracts the adverse effects of unsaturated fats.
THE INVENTIONUW–Madison researchers have developed a feed component to produce meat of better quality and longer shelf life using conjugated linoleic acid (CLA). CLA—itself an unsaturated fatty acid— actually increases the percentage of saturated fatty acid in meat. Rancid oxidation therefore is decreased and fat develops more firmly. The CLA can be isolated naturally from tallow or otherwise prepared and administered to animals, including pigs, cows, goats and poultry, as a part of their regular diet or veterinary composition.
  • Animal feed development
  • Firmer fat
  • Better sliced and longer lasting meat
  • Method allows higher concentrations of unsaturated fatty acid and vegetable oil to be fed to animals without causing adverse meat effects.
