An animal feed supplement in solid block form may be made by: (a) admixing an aqueous feed solution with solidifying and nutrient ingredients to prepare an aqueous feed supplement liquid; (b) placing a plastic bag formed of a water soluble plastic film into e.g. a vertical-walled form as a mold; (c) pouring the aqueous feed supplement liquid mixture into the plastic bag; (d) storing the mold containing the feed supplement to permit its contents to solidify; and (e) stripping the vertical-walled form from the resultant solid block to recover a solid block entirely covered by said plastic film. A solid feed supplement has total water content 10 to 35 weight percent and comprises sugar, protein, sodium carbonate, sodium bicarbonate and magnesium oxide. The sugar source may be molasses, whey, pulp and paper industry (lignin sulfonate solution) wastes or corn steep liquor. |
