Abstract
A method of preparing rumen-protected polyunsaturated fatty acids (RuPUFAs) for use in ruminant feeds by inducing the Maillard reaction between a reducing carbohydrate source and de-oiled lecithin in the presence of a PUFA under reduced pressure conditions is disclosed. Products made by the process, as well as methods for enhancing performance, assisting the induction of pregnancy, alleviating inflammation, modulating fetus growth, improving immune system function, and modulation of the fatty acid composition of meat and milk of ruminant animals are also disclosed.
Claims18
A polyunsaturated fatty acid (PUFA) supplement for use in ruminant animal feed, comprising a rumen-protected PUFA prepared by:
- mixing a reducing carbohydrate source and de-oiled lecithin with a PUFA, wherein the amount by weight of the reducing carbohydrate source is less than the amount by weight of the lecithin and is less than the amount by weight of the PUFA, optionally also including one or more of other fats, fat-soluble vitamins, or other lipophilic nutrients, to provide a mixture;
- and
- heating the mixture for a sufficient amount of time, at a sufficient temperature and under a pressure below atmospheric pressure, in the presence of sufficient moisture so that a Maillard reaction product is formed, wherein the amount of lecithin and the heating time, temperature, pressure and moisture conditions are sufficient to provide an amount of a Maillard reaction product effective to prevent ruminal degradation of said PUFA.
