We have introduced greater detail on our website’s product specifications to assist nutritionists in optimising performance. For some time, like other Feed suppliers, we have used the standard Nett Energy (MJ) included in a feed product, however the organic acid level and alcohol in many products have not been recognised in the old MJ energy calculation. For example, Brewers Yeast which states 10% DM contains 40% protein or higher, similar to Soya, but it’s in liquid which contains alcohol. The alcohol will go through the animal without utilisation if the digestibility is not factored into the energy calculation. Duynie now has the BVD MJ energy calculation which takes account of the organic acid and alcohol level – changing Brewers Yeast from NEv 7.8 MJ to NEv CVB 15.0 MJ, almost doubling its energy value and providing nutritionists greater feed efficiency.

Duynie are also beginning to publish carbon levels within our website product pages. The feed industry has been pro-active in working out carbon levels in a free to access global database of feed products. The database, produced and maintained by the GFLI (Global Feed Life Cycle Analysis Institute) is recognised widely, providing a methodology for carbon calculations which can be standardised across the global feed sector. Duynie are proud members of GFLI and use the UK Subset of data produced by AIC and GFLI to calculate the carbon levels of all our products.

Did you know that by replacing just 50% of the animal’s diet with co-products can reduce the overall carbon impact significantly? For example, in pig rations the impact of adjusting the ration to 50% inclusion of co-products can affect a 30% reduction in carbon. A 115kg Liveweight pig on a wheat, barley and soya diet and using 450kg of carbon in total, will reduce carbon use by around 150kg (30%) to 300kg.

Our website has a wealth of information for nutritionists and farmers to calculate and ration efficient use of our feeds and our sales team, supporting by a dedicated Sustainability Manager, are at hand to assist you to reduce your farm’s carbon footprint.
