Role
Primary defence against Metabolic Bone Disease. Dust feeders lightly just before offering. Choose a product with a sensible D3 level and do not stack it with other D3 sources without checking the totals. If you run a UVB lamp, use D3-containing powder less often — your vet or the product's guidance can give the exact reduction.
