Rickets is a disease of growing bones. Consequently, it usually is seen in young, weaned, growing pigs in which there is a deficiency, an imbalance, or a failure of utilization of calcium, phosphorous or vitamin D. Rickets usually is caused by a dietary deficiency of vitamin D or phosphorus. And Osteoporosis a medical condition in which the bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes, or deficiency of calcium or vitamin D. More than 10 million Americans have osteoporosis, but most do not realize that they have it.
