The DSM Vitamin Supplementation Guidelines 2016 app helps to define the right level of vitamins for eight groups of farmed and companion animal species. The guidelines also reflect the many factors influencing animals’ feed requirements, ensuring that vitamin fortification does not limit performance. Optimum Vitamin Nutrition (OVN) is centered on enabling livestock producers and pet owners to feed animals high quality vitamins in the right amounts and ratios, fitting to their life stage and growing conditions. In practice, OVN is a cost-effective range of vitamin supplementation that optimizes animal health, well-being, performance and the quality and nutritional value of animal-origin foods. This app is designed for both iPhone and iPad.
