Abstract: The invention provides novel feedstuffs for ruminants comprising an edible water insoluble salt of an edible higher fatty acid, free fat, excess of the salt-forming metal, and optionally a further nutritional material, especially a proteinaceous feedstuff such as soya bean meal. Such feedstuffs may be produced by forming a mixture of a basic oxide such as calcium oxide, a mixture of fatty acid and triglycerides, water and optionally the further nutritional material, and allowing the oxide to react with the acid to form the water-insoluble salt. The hot reacting mixture is spread out so that water evaporates spontaneously and a friable product is obtained. The process is operated continuously.
