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 prefaced 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 composition comprising:
a solidified particulate mixture of free fatty acid; and
a calcium salt of a fatty acid;
wherein the composition has an onset melt point of from 140° F. to 170° F.
2. The composition of claim 1 wherein the free fatty acid comprises tallow, non-tallow fatty acids, or a mixture thereof.
3. The composition 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 composition of claim 3 wherein the free fatty acid comprises myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, or arachidic acid.
5. The composition of claim 1 wherein the composition has a hardness of at least about 15 shore A units at 140° F.
6. The composition of claim 1 wherein the mixture of free fatty acid has an iodine number of less than 20.
7. The composition of claim 1 wherein the composition is pourable after being compressed at 3 psi for one hour at 50° C.
8. The composition of claim 1 wherein the composition can be prilled or flaked.
9. A livestock feed composition comprising:
a solid particulate livestock feed material; and
a solid particulate mixture having an onset melt point of from 140° F. to 170° F. and comprising:
a solidified particulate mixture of free fatty acid; and
a calcium salt of a fatty acid.
