Vitamin A is an essential fat-soluble vitamin that plays a central role in animal health and productivity. Adequate vitamin A supply is required for vision, epithelial tissue integrity, immune competence, antioxidant function, reproduction, growth, and overall animal resilience. While vitamin A deficiency is well understood and can result in impaired performance and increased susceptibility to disease, less attention is often paid to the quality and stability of supplemental vitamin A sources used in feed production.

Modern livestock production systems place considerable demands on feed additives. Throughout the feed manufacturing process, vitamin A is subjected to multiple factors that can compromise its stability, including extended storage in vitamin-mineral premixes, exposure to pro-oxidant trace minerals, contact with reactive ingredients such as choline chloride, elevated temperatures during conditioning and pelleting, and subsequent storage of complete feeds. These factors can significantly influence vitamin retention and ultimately the quantity of biologically available vitamin A delivered to the animal.

Consequently, achieving the targeted vitamin A concentration in the feed is not solely a matter of formulation dosage. Product quality, manufacturing technology, particle characteristics, antioxidant protection, and formulation design can all contribute to the stability and performance of vitamin A products under commercial conditions.

This presentation provides a concise review of the biological functions of vitamin A in domestic fowl nutrition and discusses why vitamin A is often considered the most important vitamin in animal production. Owing to its essential roles in vision, epithelial integrity, immune competence, cellular differentiation, growth, reproduction, and survival, an adequate vitamin A supply is fundamental for animal health and productive performance. Furthermore, the presentation will explore why quality differences among commercially available vitamin A products may have practical implications for feed manufacturers and poultry producers.

Furthermore, data from industry benchmarking studies will be presented to evaluate the performance of different commercially available vitamin A products. The benchmarking approach includes retention during premix storage, and stability under conditions representative of commercial feed manufacturing. The results demonstrate that products with identical label claims may exhibit different stability characteristics and retention profiles.

The presentation will also discuss the implications of these findings for feed formulation strategies, quality assurance programs, and economic efficiency. Higher vitamin retention throughout the feed chain may help reduce variability in micronutrient delivery and support a more reliable supply of vitamin A to the animal. This is increasingly important as producers strive for consistent performance while optimizing feed costs.

Attendees will gain practical insights into the factors that influence vitamin A performance beyond the declared activity on the product label. The session aims to support evidence-based decision-making when selecting vitamin A sources and designing feeding programs for modern poultry production systems.

By combining scientific principles with commercial benchmarking experience, the presentation will demonstrate why vitamin A quality and stability remain key considerations for successful animal nutrition in today's feed industry.
