PURPOSE: Provided is a process for the production of calcium salts of unsaturated fatty acids derived from fish oil. The calcium salts, when fed to cattle, provide reproductive benefits, in particular, an increase in fertility as embodied in an increased rate of impregnation. Also, provided are methods for providing such benefits in a ruminant. CONSTITUTION: A method for the preparation of fatty acid calcium salts is characterized by comprising: (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. |
