I wouldn’t necessarily add anything to the xkaliber. Tripe on it’s own is perfectly balanced with a calcium to phosporus ratio of 1:1. The xkaliber has additional bone which probably balances out the addition of organs in this particular blend. You would have to contact the company to get the exact numbers on the calcium and phosphorus in the the xkaliber since there is only a nutritional info link on the “tripe” product only. It seems to be a compete food in of itself. When I make a batch of food I make sure to add certain amounts of meat/organs/bone to be balanced and I’ll add some tripe. But when I feed tripe, it’s by itself. Is that confusing? I can’t seem to get into words what I mean to say!! Also you might want to introduce tripe slowly as it is high in fat – 95% fat to protein ratio!
