Lipid enrobed animal feed rations in the form of discrete feed particles or pellets (16) formed from nutritive feed ingredients and enrobed in a lipid/coagulant/water emulsion wherein the lipid enrobed rations are coated with an aqueous setting solution containing a source of metal ions to cross-bind the metal ions and coagulant, generally rendering the latter water insoluble and binding the lipid and coagulant in a stable, dry condition; and, where the resulting lipid enrobed ration comprises: i) a dry core of nutritive feed ingredients; ii) an external coating of bound lipid/coagulant in dry, stable form comprising up to, or in excess of, 20% of the overall feed ration by weight; and iii), a total moisture content which can be readily reduced to a range of from about 10% to about 13% of the total weight of the feed ration --i.e., a total moisture content which is in substantial equilibrium with the normal water of hydration level for such feed rations. The lipid enrobed particles produced are dry, stable, do not exude liquified lipids, are not prone to rancidity and/or spoilage, are free-flowing, and will not agglomerate. Processes are disclosed wherein a lipid/coagulant/water emulsion is sprayed onto the surfaces of the particles, followed by spraying of an aqueous setting solution, in either a batch or a continuous production line; and, wherein the product is dried by the application of heat which can be, at least in part, generated in the pellet compaction process and/or by preheating either the pellets or the dry feed ingredients therefore so as to render the lipid enrobed rations, at least in part, self-drying. |
