Hypocalcemia

Dietary deficiency or disturbance of metabolism of Ca, P or vitamin D including imbalance of Ca and P ratio is the principle cause of hypocalcemia. Different factors involved.

• Calcium deficiency; it may be primary or secondary

• Primary: an absolute deficiency in diet

• Secondary: when deficiency is conditioned by some other factors like excessive intake of phosphorus.

• P deficiency also primary and secondary

• Primary: an absolute deficiency in diet

• Secondary: due to excessive intake of Ca

Ca:P ratio should be 2:1 or 1:1 but in livestock 2:1 is best for absorption.

Ca functions in bone formation, milk production, blood clotting, maintenance of neuromuscular excitability. Lack of appetite, poor growth, loss of condition, infertility, low milk flow, osteodystrophies, and dental defects may develop due to Ca deficiency.
