Many nutrients are required for the normal development and maintenance of the skeleton. Bone consists of an organic matrix, made of collagen fibers and glycoproteins, and hydroxyapatite composed of calcium, phosphorus, and water. The organic matter of the bone is being remodeled by bone forming osteoblasts and bone resorbing osteoclasts. Both vitamin A and vitamin D influence osteoblasts and osteoclasts. Imbalances in these nutrients can cause skeletal deformities. Optimal nutrition for skeletal growth in young animals and for skeletal health in adult animals is therefore all about balance.
