Partial calcification of free fatty acid mixtures, livestock feed compositions including them, and methods of making same
The present invention includes a nutritional supplement composition that may be used for livestock and the like, as well as to a livestock feed mixture containing same. Also included are methods of preparing the nutritional supplement composition, the livestock feed mixture, as well as methods of providing nutrition to livestock and the like. The livestock feed composition comprises: (a) a solid particulate livestock feed material and (b) a solidified particulate mixture of (i) free fatty acid and (ii) a calcium salt of a fatty acid, the calcium salt of a fatty acid being present in a molar ratio amount in the range of from about 25% to about 55% of the amount of the free fatty acid. The preferred mixture is a solid having an onset melt point of between about 140 and 170 degrees Fahrenheit, and a hardness of from about 5 to about 15 Shore A units at 170 degrees Fahrenheit.
1. A method of improving handling characteristics of an animal feed product, the method comprising:
providing the animal feed product;
providing a partially calcified free fatty acid mixture comprising:
free fatty acid; and
neutralized fatty acid comprising a calcium salt of the fatty acid in an amount from about 25% to about 55%, on a molar basis, of total fatty acid in the mixture;
wherein the composition has an onset melt point of from 170° F. to 205° F.; and
blending the partially calcified free fatty acid mixture into the animal feed.
2. The method of claim 1 , wherein the free fatty acid comprises tallow, non-tallow fatty acids, or a mixture thereof.
3. The method of claim 1 , wherein the free fatty acid comprises a non-tallow fatty acid comprising a fatty acid from palm oil, soy oil, fish oil, linseed oil or flax oil.
4. The method of claim 1 , wherein the partially calcified free fatty acid mixture has a hardness of at least about 15 shore A units at 170° F.
