Farmers supplying Dairygold will see a 1c/l cut to their August base price.
The southern co-op will pay suppliers 27.22c/l excluding VAT based on standard constituents of 3.3% protein and 3.6% butterfat.
A spokesperson for Dairygold said: “Dairy markets continue to be challenging, with recent butter returns principally being the significant influencing factor.
"Regrettably, a downward milk price adjustment is necessary.
“The Dairygold board will continue to monitor market developments and remains focused with regard to maximising the commercial return and ensuring operational efficiency.”
Dairygold is the latest processor to cut its August milk price.
Last week, Glanbia, and Lakeland cut their prices, while this week Kerry announced an unchanged price.
