JurassiCalª Liquid is a concentrated (160,000 ppm) phosphorus free source of calcium for reptiles and amphibians. Herbivorous and carnivorous diets are frequently calcium deficient and phosphorus rich. Thus, it is of no benefit to use a calcium supplement containing phosphorus. Ideally the dietary calcium to phosphorus (Ca:P) ratio should be no less than 1.2:1 and is ideally maintained from 2:1 up to 8:1 (depending on the species). Lack of calcium in the diet can lead to metabolic bone disease and shell deformities and soft shells in turtles and tortoises. JurassiCalª Liquid is also Vitamin D3 free. Although Vitamin D3 is required for calcium processing, it could easily build to toxic levels if it were part of a frequently used calcium supplement. Vitamin D3 is more safely supplemented as part of a comprehensive and well balanced vitamin supplement like JurassiViteª. Guaranteed Analysis: Calcium (min): 15%, Calcium (max): 16%. Ingredients: calcium chlorideDIRECTIONS: BEGINNER: Lightly spray food before serving. ADVANCED: Carnivores: Spray mammals and insects with 20 squirts (0.25 mL) for every 1 g (1/32 oz) of food. Spray boneless meat and gut loaded insects with 8 squirts for every 1 g (1/32 oz) of food. Herbivores: Spray vegetables and fruits with 1 squirt for every 2 g (1/32 oz) of food. Use 2Ð4 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 our website, www.jurassipet.com. To increase calcium content by 100Êmg, use 50 squirts (0.625 mL (1/8Êtsp.)) of JurassiCalª Liquid. For larger doses it may be easier to measure directly; 5 mL (1 tsp.) adds 800 mg calcium. For example, if offering food that contains 410 mg of phosphorus and 20 mg of calcium and the desired Ca:P ratio is 2:1, you would need to add 800 mg calcium (5 mL (1 tsp.) of JurassiCalª Liquid. ADVICE: The following types of food interfere with calcium adsorption and should be avoided: phytates (soy), oxalates (spinach) and dog or cat foods.i500 mL / - UPC: 116800303
