He welcomed the news, announced on Tuesday by Lakelands, and Kerry and Glanbia on Friday.
Processors are now paying Irish suppliers 33cents per litre, this represents an increase of 1 cents per litre.
Mr. Quain then said the increases were long overdue, and added that farmers should have been paid these prices for May.
He continued by saying that while the price rise is welcomed in the dairy industry that is has effectively been a month late.
He also noted that dairy returns are remaining constant through June, except butter which is still experiencing significant rises.
He added that the feedback received by the organisation is that dairy farmers feel this price rise was “held back” a month by processors.
He said this now needs to be “rectified by meaningful increases for both June..and July supplies”.
He concluded by saying that “executives and boards would want to finally recognise that farmers can read and follow data just as easily and accurately as the co-ops and processors themselves”.
