A ruminant feedstuff comprises, in admixture, one or more edible, water-insoluble calcium or magnesium fatty acid salts and animal or vegetable protein nutritional material, the protein material having been converted during formation of the fatty acid salt into a form which is substantially non-degradable in the rumen but which is digestible in the lower gut. This feedstuff may be obtained by forming a substantially homogeneous mixture of animal or vegetable protein nutritional material, one or more fatty acids, suitably in liquid form, and a calcium or magnesium compound capable of forming an edible water-insoluble salt with the fatty acid under the conditions employed, initiating reaction of the fatty acid(s) and calcium or magnesium compound, suitably by raising the temperature of the ingredients e.g. by injection of steam into the substantially homogeneous mixture formed, maintaining the mixture at elevated temperature, e.g. 110°to 115°C., and then cooling the product. The process has the further advantage that any mycotoxins present in the nutritional material are substantially detoxified by the combined action of the high temperature and the fatty acid and base, e.g. calcium oxide, preferably used.

A process for the production of a ruminant feedstuff which process comprises continuously forming on a moving conveyor a compact mass of a substantially homogeneous mixture of animal or vegetable protein nutritional material, one or more fatty acid(s) and a basic calcium or magnesium salt capable of forming an edible, water-insoluble salt with the fatty acid(s) at an elevated temperature sufficient to initiate salt formation, maintaining the temperature processing conditions in the range of 105°to 120°C. in the compact mass on the moving conveyor until the protein nutritional material is rendered substantially non-degradable in the rumen while remaining digestible in the lower gut, and then cooling the product; wherein the compact mass has a water content of 4-18% during the salt formation reaction period. A ruminant feedstuff which comprises, in admixture, one or more edible, water-insoluble calcium or magnesium salts of one or more saturated or unsaturated fatty acids, and animal or vegetable protein nutritional material, the protein nutritional material having been converted during formation of the fatty acid salt into a form which is substantially non-degradable in the rumen but which is digestible in the lower gut; wherein the ruminant feedstuff product is produced by a continuous process in accordance with claim 1.
