BEGINNER: Lightly dust food before serving. Adheres best if food is already slightly moist.
ADVANCED: Carnivores: Dust mammals and insects with 1 g (1/3 tsp.) for every 10 g (1/3 oz) of food. Dust boneless meat and gut loaded insects with 400 mg (1/8 tsp.) for every 10 g (1/3 oz) of food. Herbivores: Dust vegetables and fruits with 1 g (1/3 tsp.) for every 400 g (about 4 cups) of food. Use 2–4 times more for turtles and tortoises and to increase calcium deposition in breeding or gravid animals.
EXPERT: Carnivores or Herbivores: Determine phosphorus and calcium content of the food and add according to desired Ca:P ratio. Values for common foods are available through selected reptile/amphibian references and on our website, here. To increase calcium content by 100 mg, add 250 mg (1/16 tsp.) of JurassiCal™. For example, if offering food that contains 200 mg of phosphorus and 20 mg of calcium and the desired Ca:P ratio is 2:1, you would need to add 380 mg calcium (1,000 mg (1/3 tsp.) of JurassiCal™). You can safely increase this amount to account for powder non-adherence loss during dusting. ADVICE: The following types of food interfere with calcium adsorption and should be avoided: phytates (soy), oxalates (spinach) and dog or cat foods.
