The Irish Farmers' Association has said the Minister for Agriculture Brendan Smith is in denial over the impact of the Government cuts on farmers.
The minister said that he did not accept claims about the impact of the cuts on farm incomes.
However, IFA President Padraig Walshe said Minister Smith is disingenuous by referring to 2008 payments, which have nothing to do with the Government's farm cuts for 2009.
This evening an estimated 7,000 thousand farmers took part in a demonstration in Ennis, Co Clare.
Farmers mostly from the west and southwest of the country attended the protest.
Around 20,000 farmers have expressed their anger over the Budget cuts at IFA meetings all over the country since October.
Mr Walshe said the way farmers have been hit is totally unacceptable.
Speaking in RTÉ, Mr Walshe said many farmers would not be able to make a living from farming.
He said the cuts are a direct attack on the viability of low-income farmers, especially in the West.
