Local farmers are planning a milk price demonstration outside Tesco in Lisnagelvin tonight.
Protests have been taking place across Western Europe against the prices paid by large supermarkets to farmers for their produce.
Locally, dozens of farmers protested against low milk prices in Strabane earlier this month. Coleraine has also witnessed huge protests.
Donemana farmer Clayton Fulton said: “This is just to get a fair price for the milk from the big supermarkets, the likes of Asda, Tesco and Lidl, who are selling the milk maybe at a loss just to get people in the door.
“It’s very bad at the minute for farmers. We’re only getting 18 pence per litre and it is set to get worse.
“We’re going to tell people about the problems we are facing.
“A lot of farmers are going to go out of business.
“We’re out £1,800 to £1,900 a month over the head of this, from feeding the stock, electricity, everything.
“We can only keep that going for so long.”
