Abstract
A preparation for administration to animals, comprising a sparingly soluble L-ascorbic acid-2-phosphoric ester salt having a solubility in water of 10 wt % or less, the solubility being a value obtained by placing 100 g of purified water in a 200 ml-volume beaker, stirring the water while keeping the temperature at 20° C., adding 0.1 g of the L-ascorbic acid-2-phosphoric ester salt every 5 minutes by taking care not to cause gelation, and 30 minutes after the addition of L-ascorbic acid-2-phosphoric ester salt when the undissolved L-ascorbic acid-2-phosphoric ester salt is observed visually in the aqueous solution, determining the amount in weight percentage of L-ascorbic acid-2-phosphoric ester salt added based on water, and a method for feeding animals, using the preparation.
