Abstract

Fats and oils are used for many purposes in animal feeds and pet foods, including the following:

  • Increasing caloric density of feeds (by about 2.25 times that of similar dry weights of proteins or carbohydrates).

  • Improving feed palatability and appearance.

  • Reducing total feed intake, increasing feed efficiency, and minimizing feed costs.

  • Increasing blood glycogen levels and endurance in working animals like horses and sled dogs.

  • Lowering the heat of reaction during digestion and metabolism—important for comfort and productivity of large animals in hot weather.

  • Delaying digestion of feedstuffs beyond the rumen by use of inert forms of fats and coatings.

  • Providing needed molecular structures through dietary essential fatty acids (EFA) and phospholipids.

  • Improving appearance of skin and hair, and prevention of dermatitis.

  • Modifying fatty acid profiles in “designer food” animal products.

  • Carrying fat-soluble vitamins and color compounds.

  • Binding heat-sensitive flavorings, vitamins, medications, and “instant gravy” mixes to pet foods and feeds after extrusion or drying.

  • Improving dispersion of dry mixes, e.g., lecithin in calf milk replacers.

  • Preventing segregation of mixed feeds.

  • Reducing dustiness of feeds and feeding operations and of grain elevator dust.

  • Lubricating feed processing machinery.
