“…The stability and bioavailability of vitamin A from pet food and animal feed formulations can vary depending on factors such as the vitamin A formulation (from a commercial source), the ingredient composition, processing methods, and storage conditions [110,[234][235][236][237]. Systematic assessments of vitamin A bioavailability in commercial pet foods are necessary to ensure adequate nutrient delivery and to optimize dietary formulations for pet health and wellness.…”

The health of companion animals, particularly dogs and cats, is significantly influenced by nutrition, with vitamins playing a crucial role. Vitamin A, in particular, is indispensable, with diverse roles ranging from vision to immune modulation and reproduction. Despite its importance, the metabolism and dietary requirements of vitamin A in companion animals remain complex and not fully understood. This review provides a comprehensive overview of the historical perspective, the digestion, the metabolism, the physiological roles, the deficiency, the excess, and the interactions with other micronutrients of vitamin A in companion animals. Additionally, it highlights future research directions and gaps in our understanding. Insights into the metabolism of vitamin A in companion animals, personalized nutrition strategies based on genetic variability, longitudinal studies tracking the status of vitamin A, and investigations into its immunomodulatory effects are crucial for optimizing pet health and wellness. Furthermore, understanding the stability and bioavailability of vitamin A in pet food formulations is essential for ensuring the provision of adequate micronutrients. Overall, this review underscores the importance of vitamin A in companion animal nutrition and the need for further research to enhance our understanding and to optimize dietary recommendations for pet health and well-being.

Vitamin A is essential for poultry health, influencing vision, growth, antioxidant defense, reproduction, and immune function. However, it is highly sensitive to degradation when exposed to light, moisture, heat, and oxygen. To address this, vitamin A is typically formulated as retinyl acetate in small beadlets. These beadlets are commonly included in premixes for industrial poultry diets. However, variations in beadlet formulations among different producers can lead to differences in stability and bioavailability, potentially impacting their effectiveness and biological value for poultry. Understanding the stability and bioavailability of various vitamin A sources is crucial for optimizing poultry feeding strategies and ensuring adequate vitamin A supply. The stability of vitamin A can be evaluated through several methods, including premix stability, stability during pelleting, storage stability in feed, and the stability of pure vitamin A products. Bioavailability, which reflects how effectively vitamin A is absorbed and utilized by the animal, is typically assessed through in vivo studies, with liver retinol levels serving as a key indicator. To enhance poultry production, it is important to select vitamin A sources that offer both high stability and bioavailability. Effective feed management, including the use of stable and readily absorbed forms of vitamin A, can improve poultry health, growth rates, and overall production efficiency.
