Vitamins are the foundation of balanced animal nutrition. They are essential, irreplaceable nutrients that are required for normal physiological functions including growth, body development and reproduction, as well as animal well-being and general health status. Most vitamins cannot be synthesized by animals and must be obtained by feed; however, feed alone is not enough to ensure the right vitamin status. This is due to multiple factors such as: low and/or variable vitamin levels, limited bioavailability, storage conditions and treatments applied to feedstuffs during feed manufacturing. This can lead to decreased vitamin status in animals. Lower animal performance, poor health and immunity, reduced reproductive success and even mortality are some of the consequences of vitamin deficiency which can have a serious cost impact on animal production.
