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.

The disclosure relates to isolated microorganisms—including novel strains of the microorganisms—microbial consortia, and compositions comprising the same. Furthermore, the disclosure teaches methods of utilizing the described microorganisms, microbial consortia, and compositions comprising the same, in methods for modulating the production and yield of milk and milk components in ruminants. In particular aspects, the disclosure provides methods of increasing desirable components of milk in ruminants. Furthermore, the disclosure provides for methods of modulating the rumen microbiome.
