Preparation for administration to animals and feeding method thereof

摘要

Preparations for administration to animals comprising a sparingly soluble L-ascorbic acid-2-phosphoric ester salt with a solubility in water of 10 weight % or less. Preparations for administration to animals comprising a sparingly soluble L-ascorbic acid-2-phosphoric ester salt with a solubility in water of 10 weight % or less. The solubility is a value obtained by placing 100 g of purified water in a 200 ml beaker, stirring the water while keeping the temperature at 20[deg]C, adding 0.1 g of L-ascorbic acid-2-phosphoric ester salt every 5 minutes by taking care not to cause gelatin and, 30 minutes after the addition of the 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 its amount as a weight percentage of L-ascorbic acid-2-phosphoric ester salt added based on water.
