Which vitamin is crucial for maintaining poultry health?

Vitamin A plays a significant role in maintaining poultry health, as it is essential for several critical bodily functions. This vitamin is crucial for normal vision, immune system function, and reproductive health. In poultry, it supports the growth and development of the epithelial tissues, including those lining the respiratory and digestive tracts, thereby playing a protective role against infections. Additionally, vitamin A is involved in the synthesis of certain hormones and is necessary for the maintenance of skin and mucous membranes.

While vitamin C, B12, and K also contribute to poultry health—by aiding in the formation of red blood cells, playing roles in metabolism, and promoting proper blood clotting respectively—they do not have the same broad and vital implications for overall poultry health as vitamin A. Poor vitamin A availability can lead to serious health issues in poultry, highlighting its importance in their diet and well-being.
