Dairy cows feeding

Upcoming targets to reduce atmospheric pollution will require improved nitrogen use efficiency within the dairy sector, and better feeding has a key role to play.

Clean Air Strategy targets are for a 46% reduction in atmospheric particulates by 2030, with both ammonia and nitrous oxide key contributors to that pollution. Better balancing nitrogen and energy supply in the rumen can improve nitrogen use efficiency and cut nitrogen excretion.

According to CEDAR research, improved formulation can allow dairy ration crude protein content to be cut from 18% to 16% with no loss in cow performance, for potentially lower ration costs and higher margins.

Key facts & figures:

  • Around 75% of nitrogen fed to dairy cows is excreted in urine or faeces

  • Better balance RDP1 and rumen energy supply to maximise nitrogen capture

  • Better balance RDP1 and rumen energy supply to maximise nitrogen capture

  • Best value sources of rapidly available sugars include Molale and Economol

  • Sodawheat, SweetStarch and SugaRich Dairy good options for starch

  • Use DUP2 from NovaPro, ProtoTec or SoyPass to top up cow requirements

1 Rumen degradable protein
2 Digestible undegraded protein
