DEFICIENCY SYMPTOMS -  RICKETS / OSTEOMALACIA

• If calcium is deficient in the diet of young growing animals, then satisfactory bone formation cannot occur and the condition known as rickets is produced. 
• The symptoms of rickets are misshapen bones, enlargement of the joints, lameness and stiffness.
• In adult animals, calcium deficiency produces osteomalacia in which the calcium in the bone is withdrawn and not replaced. 
• In osteomalacia the bones become weak, fragile and are easily broken.
