Vitamin A is a fat-soluble vitamin and essential micronutrient for poultry. When added to the diet it is converted to retinoid within the intestine, liver, and other tissues.
Vitamin A is required for birds to maintain a healthy immune system and integrity of all internal organs and body systems, including oral, respiratory, urogenital, gastrointestinal, cardiovascular, and renal health.
When Vitamin A is low or absent from the diet, the cells undergo changes that prevent the secretion of mucous, thus destroying a critical line of defense against bacterial invasion.
