Environmental and nutritional benefits of bioethanol co-products (ENBBIO)

Home \ Research & Innovation \ Research \ Environment \ Environmental and nutritional benefits of bioethanol co-products (ENBBIO)

The ENBBIO LINK project was a collaboration involving 25 industry and academic partners, sponsored by Defra through the Sustainable Livestock Production LINK programme.

Project duration: 2010 – 2013

 

Aims and objectives

  • To quantify the chemical composition of UK wheat Dried Distillers Grains with Solubles (W-DDGS) and other co-products
  • To identify the limitations associated with feeding W-DDGS
  • To identify routes to improving nutritional value of DDGS
  • To test the modified and improved DDGS products using ruminant and non-ruminant species
  • To quantify the overall benefits of DDGS production on reducing diffuse pollutants and enhancing home-grown protein production 

Findings to date

  • DDGS has been shown to be a valuable source of protein for the livestock industry
  • W-DDGS from a modern bioethanol plant is very consistent in quality and the protein content of it is less variable than the original wheat used at intake
  • W-DDGS has been used to successfully replace a significant proportion of the soya protein in poultry and dairy diets; analysis to understand animal responses and commercial value is ongoing
