Abstract: A process of producing a ruminant animal feed by mixing calcium ammonium lactate sediment derived by precipitation from fermented ammoniated condensed whey, with calcium sulfate and drying the mixture in contact with air.

Abstract: Crystalline calcium ammonium lactate dihydrate, a constituent formed from fermented ammoniated condensed whey, and is useful as a nutrient for ruminant animals.

Abstract: Fermented ammoniated condensed whey (FACW) is solidified by mixing it with certain calcium salts and allowing the mixture to stand. The mixture, while still liquid, may be mixed with grains, roughage and forage materials, or it may be shaped into blocks, cubes or pellets. Solidified FACW can be used as a feed supplement for ruminant animals. During the solidification calcium ammonium lactate is formed which is a new crystalline chemical composition. Calcium ammonium lactate (CAL) may be prepared in purified form from lactic acid, calcium hydroxide and ammonia. CAL is useful independently as a feed supplement for ruminant animals.
