Aim: to Develop feeds and feeding strategies that result in reduced nitrous oxide emissions.
What does success look like?
Low nitrous oxide feeds and strategies adopted on farm
How will we get there?
- Understand feed options to reduce urinary nitrogen output
- Understand feed options to reduce the nitrous oxide emission factor of urinary nitrogen
- Analyse the potential of alternative forage species to reduce nitrous oxide
- Identify natural nitrous oxide inhibitory compounds (as appropriate)
What input is needed?
Science is needed to identify and provide proof of concept of feed options that reduce urinary nitrogen, nitrous oxide and nitrogen leaching.
Commercial input will be needed to promote feeds and feeding strategies to industry.
Commercial input will also be needed if natural nitrous oxide inhibitors are identified to undertake breeding programme.
What's the timeline?
"COMPOUNDS IDENTIFIED FOR REDUCING N2O EMISSIONS: Lab and field trials from the two PhD programmes on the effect of diet-induced urine composition on N2O emissions, have revealed two potential compounds for reducing N2O emissions. A comprehensive lab study using glycosinolate hydrolysis products that can be found in brassica crops, has shown that some compounds can reduce nitrification and lower N2O emissions.
Similarly, a lab study using aucubin, a key compound in plantain, showed that aucubin could also lower N2O emissions."
