DSM in Animal Nutrition & Health

Check vitamin levels in animal feed. Always.

All ingredients in animal feed are regularly evaluated and likewise vitamin levels and ratios require the same degree of attention. We therefore encourage the feed industry and all other stakeholders to check the vitamin levels in their animal feed. Always.

Optimum Vitamin Nutrition (OVNTM) is about feeding animals high quality vitamins in the right amounts and ratios appropriate to their life stage and growing conditions. To accomplish this, we are intensely engaged in research and development and we focus on partnering with all important stakeholders – leading scientists, universities, genetics companies, independent research institutes, and customers. This enables us to develop and produce a complete line of high quality vitamins and support the feed industry with the DSM Vitamin Supplementation Guidelines.

OVN™ levels compensate for the many factors which can influence animals' requirements and corresponding feed levels, thus ensuring that vitamin fortification does not limit performance. OVN™ levels are ranges for consideration, depending on a range of factors, such as husbandry conditions. They are based on extensive university and industry research, published requirements and practical experience.

The vitamin amounts stated are those which should be provided to the animal in the feed at the point of consumption. Additional vitamins should be added to the product to account for processing and shelf-life storage losses to achieve the targeted consumption amounts of vitamins. These losses can be variable. Please ask your local DSM representative for information about typical levels of process and storage loss.
