Fats & Oils

Fats and oils used in animal feed vary widely in their physical properties. Natural vegetable and animal fats are made up of triglycerides, which are esters of glycerol and fatty acids. The hardness or softness of fats is in direct relationship to the fatty acid profile of the lipid. The more saturated fatty acids, the harder the fat; the more unsaturated, the softer. Iodine value (IV) is a measurement of the hardness or softness of the fat and is defined as the grams of iodine absorbed by 100 grams of fat. Unsaturated fats have a higher IV than saturated fats. Thus, the higher the IV of a fat is, the softer the fat.

The most common feed fats are:

• Tallow - derived primarily from the rendering of beef offal.
• Choice white grease - derived primarily from the rendering of pork offal.
• Poultry fat - derived from poultry offal.
• Feed grade animal fat - derived primarily from a mixture of rendered beef, pork, and/or poultry raw material.
• Yellow grease - derived primarily reprocessed restaurant grease/cooking oil.
• Blended animal-vegetable fat - can include blends of different types and amounts of animal fats, vegetable oils from restaurant grease.

MOPAC's rendered animal fats and blended fats are produced from high-quality ingredients. These fats and oils are tested for pesticide residue so our customers can be assured our products are contaminant-free. Antioxidants are added to the feeding fats to insure stability of the fats in feeds and storage.

Poultry Feeds

Feeding fats provide a concentrated source of energy, but there are other reasons for using fat such as improving the physical characteristics of the feed.

• Fat decreases dustiness (feed loss is reduced by effective dust control).
• Fat improves palatability of feed.
• Fat increases lubrication value of feed.
• Fat reduces particle separation (helps maintain uniform mixture of the ration).
• Contributes an essential fatty acid, linoleic acid.

MOPAC fats commonly used in poultry feed are: (1) RenTech (animal-vegetable blend), (2) Feed Grade Animal Fat and (3) Poultry Fat.

Dairy Cattle Feeds

Along with improving the physical characteristics of feed by reducing dustiness and increasing energy density, feeding supplemental fat in dairy rations will enhance lactation performance in several ways.

• Adding MOPAC Rendering fats to the diet will help reduce the negative energy balance during early lactation of high producing dairy cows.
• The appropriate amount of fat in the diet approximates that produced in the milk by providing fatty acids to the udder.
• Unsaturated fats (vegetable oils) are less desirable for dairy cattle because of their inhibiting effects on rumen fermentation and digestion. Animal fats, which are more saturated, and blended animal-vegetable fats, generally yield the most positive response in animal performance.

MOPAC fat commonly used in dairy cattle feed is bleachable fancy tallow. Tallow is considered safe by the FDA for use in dairy feed and is exempt from FDA's ruminant feed regulation. We assure that all BFT sold has insoluble impurities not exceeding .15% by volume.
