Calcium Salts of Fatty Acids - Feed Ingredient

Calcium salts of fatty acids, also known as rumen-protected fats or calcium soaps of fatty acids, are compounds formed by reacting free fatty acids with calcium, typically calcium hydroxide. These salts are used in animal feed formulations as a concentrated energy source.

The manufacturing process involves saponification, where fatty acids—commonly derived from vegetable oils like palm or soybean oil—are reacted with calcium to produce an insoluble, dry, granular product. This form allows for easier handling and incorporation into feed and helps prevent rancidity associated with free fats.
