Colored animal feeds, especially red and blue feeds, promote weight gain in animals, particularly poultry and swine. Colored feeds particularly promote weight gain in the first seven days leading to much improved weight at shipping. A concentrate having from about 1 wt% to about 15 wt% of a physiologically acceptable feed consumption enhancing food-coloring agent compatible with animal feed ingredients, from about 2 wt% to about 20 wt% of a physiologically acceptable electrolyte compatible with animal feed ingredients, and balance a physiologically acceptable carrier can be conveniently used to prepare colored animal feed on an industrial scale at any of various points in the milling or post- milling process. |
