SPECIAL STORY FEED & ADDITIVE MAGAZINE September 2023 77 dsm-firmenich, as part of our sustainability commitment, has developed Environmental Vitamin Product Declarations (EPD) which transparently provides environmental footprint information to support purchasing decisions and to support feed millers, integrators, and farmers to better assess product sustainability. These environmental product reports may be soon part of the industry specifications according to their individual needs and commitment to sustainability in the feed and food chain. Reducing the carbon footprint of vitamin and other feed additive operations, enable feed millers, integrators, and farmers to become more sustainable, reduce their risk profile and to potentially benefit from value created from future carbon tax savings (Figure 5a and 5b). CONCLUSION Supporting swine diets with appropriate vitamins help make farming more sustainable. Optimum Vitamin Nutrition® (OVN™) is about feeding animals high quality vitamins, produced with the lowest environmental footprint, in the right amounts, appropriate to their life stage and growing conditions, to Figure 5a.
