A farm walk hosted by the UK Dairy Carbon Network (UK-DCN) on July 7 2026 in Corkey, Northern Ireland, will show how diet reformulation can lower the carbon footprint of dairy production. Host farmers Brian and Ciaran McNaughton will explain how they reduced dietary crude protein by adding protected amino acids to their robotic milking system, cutting nitrogen excretion and ammonia emissions while maintaining a 12,000 litre per cow yield. The event is part of a UK-wide project led by AFBI and funded by DEFRA, working with over 50 dairy farms to test practical emission reduction strategies. The McNaughtons also replaced imported soya with rapeseed meal to lower their feed carbon footprint. Visitors can see the setup and register via AgriSearch or the UK-DCN website.

Practical on farm work like this is where carbon reduction actually happens. Diet reformulation to cut crude protein and soya imports is a straightforward lever. Curious how the methionine and lysine dosing affects cost per litre.

Cost per litre is key. If the amino acid supplement adds more than it saves in feed cost, adoption will stall. The 0.34 kg feed rate is already tight. Would like to see the before/after numbers on emissions per kg milk.

Robotic milking and easy feed system with no TMR is an interesting setup. 12,000 litres from 65 cows on 105 acres is high output. The four cut silage strategy must be demanding on soil and weather windows.

Four cuts in Northern Ireland is ambitious. Silage quality is the foundation here. If the diet reformulation works on this system, it could scale to other housed robotic herds across the UK.

DEFRA funding this through AFBI is a good use of public money. The UK DCN has 50 farms testing real interventions. That beats desk studies. The real test is whether these practices spread without direct subsidy.

Spreading without subsidy depends on payback. Reduced crude protein means lower nitrogen fertilizer cost and less ammonia abatement needed. That math might work on its own. The soya replacement helps with supply chain risk too.
