‘The way HDM calculated the percentages of the calcium is from usuing this formula
1)Multiply calcium% by 1000g. That gives you the grams of calcium/kg
2)Divide the grams of calcium/kg by the kcal/kg for the food. That gives you the grams of calcium/kcal.
3)Multiply the grams of calcium/kcal by 1000/1000. That gives you grams of calcium/1000kcal.
Ive calculated food that say the max calcium is 1.5% but after the calculations the food was over the 3.5g of calcium per 1000kcal’
This is exactly why I’m still so uncomfortable feeding raw to my large breed pups! The whole point it doing it is to give them the best nutrition but if I screw up the calcium/phosphorus ratio etc I’ve just caused a problem that could be serious. And it seems fairly complicated to get it right. I’ve used a couple of books that are helpful but I can’t ask specific questions. This forum has helped tremendously but I’m still so insecure about it. Looking forward to the Raw Feeding Web Conference next weekend.
In the meantime does anyone know a good place to get nutritional values for various meats that include the bone, as well as green tripe etc? I found a website that I can use to add ingredients and get total values but, of course, the only items already in the database do not contain bone, etc. There’s a small fee if you want to do more than 3 recipes but if it help me get this right, it’s worth it :).
