Abstract: An improved molasses feed block is provided that is water resistant, non-porous, hard and vitreous. Said feed block is generally manufactured by the following method. A fluid feed composition is provided comprising molasses, unsaturated free fatty acids and an amount of a bivalent base sufficient to saponify said fatty acids into an insoluble soap to enhance the water resistance of said feed block. Lecithin is also added to reduce the stickiness of said composition. A nutritionally compatible acid or base is added to maintain the pH of said composition between about 6.2 to about 6.8 to reduce swelling in said feed block. A dry meal flour is added to provide nutritional values to said feed block and to reduce the swelling of said feed block by reducing its temperature.
