Magnesium Deficiency

Hypomagnesemia

Magnesium (Mg) is an essential mineral that is required for bone formation, carbohydrate metabolism, and for activation of several enzymes. Severe magnesium deficiency can impede vitamin D and calcium homeostasis; leading to an increased risk of osteoporosis, metabolic disorders, and cardiovascular diseases. In young chicks, deficiencies can cause stunted growth, lethargy, convulsions and death.
