vitamins a&d

Has anyone used Phos-Aid. What is the dosage for a goat. If given a 2nd time, how long between shots? Also, I have injectable Vitamins A&D. It has 500,000 IU Vitamin A & 75,000 IU Vitamin D3 in each ML. Bottle does not list dosages by weight. It just has dosages for mature cows, yearling cows...
