If you’ve been feeding Prey Model Raw levels of liver (5%) I’d suspect the cause of the Osteomalacia was due to an imbalance in calcium to phosphorus levels in the diet, as opposed to insufficient Vitamin D.
Feeding 10% bone (as the PRM calls for) should keep Ca:P near the optimal 1.2:1 ratio. Unfortunately too many raw feeders are contemptuous of the need to maintain the correct mineral balance by carefully considering the amount of meat vs bones (and organs) are being fed, and too often too much bone gets fed as a result. Too little bone (relative to meat) can also be a problem with Osteomalacia.
I’d advise doubling down on your understanding of the edible bone content in the ingredients you are feeding with a determined effort put into balancing the calcium:phorosphus ratios in the diet, as this is the likely source of the problem.
