The relationship between vitamin A status and oxidative stress in animal production
ABSTRACT Oxidative stress is caused by an imbalance between the production of harmful oxygen molecules and the body's ability to repair their detrimental implications, leading to reduced growth rates, increased disease susceptibility, and decreased reproductive performance in animals. Vitamin A, comprising retinol, retinal, and retinoic acid, is crucial for normal growth, reproduction, and vision. Vitamin A possesses antioxidant properties by directly scavenging reactive oxygen species, boosting antioxidant enzyme activity, and promoting antioxidant defence mechanisms. Numerous studies have shown that livestock with adequate levels of vitamin A in their diet experience reduced oxidative stress compared to those with vitamin A deficiency. Moreover, vitamin A supplementation can mitigate oxidative stress in animals exposed to stressful conditions like heat stress. Adequate vitamin A status in livestock through dietary interventions and improved animal management practices can significantly benefit animal health and well-being. However, further research is still needed to optimize dosing strategies and fully understand the relationship between vitamin A and oxidative stress in different animal species and production systems. Therefore, continued research efforts are essential to fully harness the potential of vitamin A as an effective tool for mitigating oxidative stress and improving animal welfare.

期刊介绍: Journal of Applied Animal Research (JAAR) is an international open access journal. JAAR publishes articles related to animal production and fundamental aspects of genetics, nutrition, physiology, reproduction, immunology, pathology and animal products. Papers on cows and dairy cattle, small ruminants, horses, pigs and companion animals are very welcome, as well as research involving other farm animals, aquatic and wildlife species. In addition, manuscripts involving research in other species that is directly related to animal production will be considered for publication.
