Over the past three weeks, we have been running a special series looking at the performance of Irish dairy co-ops. Week one showed a differential of 6c/l in the milk price paid by the top and bottom performing co-ops.

There are of course some legitimate reasons for the differential – the main one being the decision by the top-ranking co-ops to pass back a dividend through the milk price from their non-core dairy businesses, but typically this accounts for less than 2c/l.
