Dozens of farmers are protesting in Ballinasloe, Co Galway as part of an ongoing series of nationwide protests outside meat processing plants.
The Beef Plan Movement are calling for what they say is a "fair increase" in cattle prices and say they will continue to picket factories until the government intervenes.
Farmers protesting outside Liffey Meats say rural Ireland is being decimated and recent trade deals are the final nails in the coffin.
The protesters, who have been outside Liffey Meats overnight, say they have endured years of squeezed profit margins at the expense of retailers and processors who they say are making big profits.
The Beef Plan Movement has issued guidelines to members on carrying out peaceful demonstrations following a number of incidents between protesters and fellow farmers at picket lines around the country.
Some factories have suspended cattle killing as the Beef Plan Movement encourages farmers not to present animals for slaughter. But farmers are under pressure to move stock and there are still significant numbers being traded.
The organisers of the Beef Plan Movement say they set up the group because of what they described as "the failure" of their largest union, the IFA, to meet their needs.
