Irish farmers are very well-educated and the market place in Ireland is "slowly" changing, Mulvihill says.
"We currently export 90pc [of dairy produce] and we will be moving towards 95pc exports, this will serve to drive competitiveness.
"If, and when, the Lakeland-LacPatrick merger is agreed, 80pc of the milk in Ireland will be in the hands of four huge processors - Kerry Group, Glanbia, Lakeland, and Dairygold." That sentiment is echoed by Jim Mulqueen, partner at Grant Thornton, who expects continued consolidation in the sector as margins come under increasing pressure.
"There are regular discussions among certain co-ops around consolidation," he says.
"We also see opportunities regionally for maybe neighbouring co-ops, or co-ops with the same sector focus, to operate together."
The main reasons behind this, he says, is typically cost savings and synergies, all of which add to a business's bottom lime, and help a company run more efficiently.
"It not as simple as taking the profit of one company and the profit of another, and having a bigger profit, some of it could be strategic in terms of location, but typically cost-saving, synergies."
Mr Mulqueen does not, however, think that Ireland will go the same way as the likes of Denmark and New Zealand, partly because the Competition and Consumer Protection Commission will be watching from the wings.
"I could see some resistance at local level to increased consolidation in the market place, but I think that before we get to having one or two super milk producers the Competition Authority will step in if they feel competition is being eroded.
"They are the appropriate watchdog, and they will ensure that competition is maintained," he said.
From a farmer's perspective, Tom Phelan, chairman of the Irish Farmers Association (IFA) dairy committee, says that any merger between co-ops has to deliver for farmers, both in terms of better prices and better use of existing facilities.
"In the future we have to focus on adding value to milk, there is no point expanding for the sake of expanding," Mr Phelan said.
The Laois-man added that co-ops are democratically run, noting that the LacPatrick merger is still subject to membership votes - the amalgamation between the two will depend on the wishes of farmers.
"What the IFA want to see is the maximum benefit got for the farmers, be it though mergers, acquisitions, business co-operation and so forth."
On the matter of Brexit, Mr Mulvihill describes it is a "disrupter" for the industry, which will serve to "concentrate minds". However, he says that it is hard to determine whether it will lead to an increase in mergers and acquisitions in the sector.
"We would actually see climate change and environmental issues as the biggest challenge facing the industry right now," he said.
Should a hard Brexit occur, of particular concern to dairy farmers and producers in Ireland will be the exposure of Irish cheddar in the UK.
On this Mr Mulvihill says that there has been a lot of investment by processors away from cheddar.
In July, Glanbia Cheese, the Joint Venture business between Glanbia PLC and Leprino Foods, announced plans to build a new mozzarella cheese manufacturing facility in Portlaoise.
A total of €130m will be invested in the facility, which will have a production capacity of 45,000 tons per year.
Similarly, Mr Mulqueen said that Grant Thornton are seeing a number of the bigger players, the likes of Ornua, Dairygold, and Total Produce, looking beyond the UK market to other regions.
"We see that larger companies are quite well prepared for Brexit in terms of scenario planning and so on, but some of the smaller players in the market would still be adopting a level of wait and see, they simply don't have the bandwidth and time, and will try and adapt as things happen."
