Which elements are classified as macro minerals in poultry nutrition?

In poultry nutrition, macro minerals are essential nutrients that are required in larger quantities for optimal growth, development, and overall health of birds. Calcium (Ca), phosphorus (P), and magnesium (Mg) are indeed key macro minerals.

Calcium plays a critical role in bone development and is vital for eggshell formation in layers. Phosphorus is equally important as it contributes to energy metabolism, bone health, and various biochemical processes within the body. Magnesium also supports bone structure and is involved in many enzymatic reactions that facilitate the utilization of other nutrients.

Therefore, the answer that includes all three minerals—calcium, phosphorus, and magnesium—correctly identifies these essential elements that are classified as macro minerals in poultry nutrition. Recognizing the significance of each of these minerals reinforces the understanding that they must be present in substantial amounts in a poultry diet to ensure the health and productivity of the birds.
