Here’s a recipe I received from Saga earlier: Daily portion for Ask (965 kcal): Main ingredients (ready-prepared weight): Sei (Pollock): 526 g White rice (cooked): 365 g Pumpkin (cooked/pureed): 113 g Blueberries: 26 g Supplements and fat sources: Wheat germ oil: 13.2 g (Important source of vitamin E and linoleic acid) AniForte Canine Complete: 9.7 g Avital Calcium: 4.9 g (safe source of calcium without chicken protein) BioLife Zinc (14 mg): 1.3 tablets Nycoplus Vitamin D3 drops (80 IU): 2.5 drops

• "I have made a base of 4 kg of saithe, rice and pumpkin for Ask. The recipe said 110 g of Avital Calcium, but I want to use homemade eggshell powder instead. How many grams of eggshell should I use to get the right balance for 4 kg of saithe?"
• Hi Hanne 😊 Avital Calcium contains 36% calcium, while ground eggshells contain approximately 360–400 mg of calcium per gram, i.e. around 36–40% elemental calcium. This means that eggshells contain approximately the same amount – and in some cases slightly more – calcium per gram than Avital. The difference is therefore very small and within natural biological variation. When converting from Avital to eggshells, the ratio will therefore be approximately 1:1 in grams.

Regarding vitamin A: The diets are designed to be complete and balanced, so by removing Canine Complete, you are also removing several other essential nutrients (not just vitamin A). It usually takes time for dogs to de…
