Union has called for farmgate milk prices to rise significantly in order to make up for the recent surge in input costs, many of which are linked to the war in Ukraine.
The supply chain should pay more to fully reflect the 'unsustainable' input costs caused by increases in feed, fuel, fertiliser and energy costs, the Farmers' Union of Wales (FUW) said.
It recently wrote to the UK's major retailers urging them to ensure that rising input costs do not threaten the long term viability of food producers in the UK.
Farmers should also be paid a fair price for their produce in light of the developing circumstances in Ukraine.
Speaking after union's recent milk and dairy produce committee meeting, Dei Davies, committee chairman, said that increases in UK food prices were inevitable.
"While retailers do have a part to play, we must ensure that this is reflected throughout the supply chain and reaches the farm gate.”
