A method for the preparation of fatty acid calcium salts, which includes the steps of: (a) providing a fatty acid feedstock having a glyceride content between about 30 and about 60% by weight; (b) adding to the feedstock from about 2 to about 3 equivalents of calcium oxide relative to the feedst

A method for the preparation of fatty acid calcium salts, which includes the steps of: (a) providing a fatty acid feedstock having a glyceride content between about 30 and about 60% by weight; (b) adding to the feedstock from about 2 to about 3 equivalents of calcium oxide relative to the feedstock, so that a reactive admixture is formed; and (c) adding to the reactive admixture from about 2 to about 5 equivalents of water relative to the calcium oxide so that the calcium oxide hydrates and neutralizes the fatty acids to form calcium salts. Fatty acid calcium salts containing eicosapentaenoic acid and docosahexaenoic acid are also disclosed, as well as methods for enhancing ruminant fertility.

1. A free-flowing fatty acid calcium salt product comprising from about 1 to about 10% by weight of eicosapentaenoic acid (EPA) and from about 1 to about 10% by weight of docosahexaenoic acid (DHA), and having a residual glyceride content below about 5 weight percent. 2. The product of claim 1, having a fatty acid profile consistent with a profile resulting from blending from about 15 to about 50% by weight of one or more fish oils with from about 85 to 50% by weight of PFAD. 3. The product of claim 2, wherein said fish oils are derived from one or more fish oil sources selected from the group consisting of menhaden, herring, mackerel, caplin, tilapia, tuna, sardine, pacific saury and krill. 4. A method for increasing fertility in a ruminant, comprising feeding said ruminant an effective amount of the product of claim 1. 5. The method of claim 4, wherein said ruminant is a female ruminant. 6. The method of claim 5, wherein said female ruminant is a dairy cow. 7. The method of claim 5, comprising starting the feeding of said product to said female ruminant between about 21 days before and about 28 days after parturition. 8. The method of claim 7, wherein said feeding of said product to said female ruminant is continued at least until conception occurs. 9. The method of claim 5, wherein said product is fed to said female ruminant daily. 10. The method of claim 8, wherein said product is fed to said female ruminant for at least 30 days after conception. 11. The method of claim 10, wherein said product is fed to said female ruminant for at least 60 days after conception. 12. The method of claim 11, wherein said product is fed to said female ruminant for at least 150 days after conception. 13. The method of claim 8, wherein the feeding of said product comprising EPA and DHA is discontinued at conception or within 150 days thereafter and said method further includes the step of feeding daily to said female ruminant a fatty acid calcium salt product for supplying milk production energy to a female ruminant after the feeding of said product comprising EPA and DHA is discontinued.
