In 1966 Ballyhale Co-Operative Creamery Dairy Society Ltd., formed by local farmers, had joined with other small rural co-operative societies from Kilkenny and some neighbouring counties and, together with Unigate Limited support, formed the Avonmore Creameries Federation Realising the benefits of increased scale and greater diversification in the 1960s, they saw the need for an amalgamation of many small, locally focused co-operatives across Ireland. It led to the construction of a new multi-purpose Avonmore dairy plant facility in Ballyragget, County Kilkenny, and a Plant they claimed was the biggest food processing facility in Europe at that time. Today that giant global entity is known as Glanbia. Glanbia has its origins in the Irish agricultural co-operative movement that evolved over the last century since first Irish Co-operative in 1889, founded by Horace Plunkett. Ireland entered the Common Market in 1970.
