Processors in Ireland have announced their milk prices for farmers for March supplies over the last two weeks.
Most recently, yesterday (Monday, April 20), Carbery Group announced an increase in its base milk price for March.
The processor has announced an increase in its base milk price of 3c/L.
As well as that, Carbery also announced that it will make a payment of 1.5c/L from its Stability Fund.
Carbery said that if its base milk price increase is replicated across the four west Cork co-ops of Bandon, Barryroe, Drinagh, and Lisavaird, this will result in an average milk price of 40.80c/L, including VAT, a 0.5c/L somatic cell count (SCC) and the FutureProof sustainability bonus.
Based on actual milk solids, the price paid for March milk will be 45c/L, including VAT, the processor said.
A spokesperson for Carbery Group said: "We are not seeing the improvement in dairy markets that we would like, and supply continues to impact on prices being delivered.
"However, we recognise the importance for our farmer shareholders of delivering the maximum milk price, especially as we head into peak milk production months," the spokesperson added.
