Demand for Irish beef in key markets is driving prices as supplies remain tight, the Irish Farmers' Association (IFA) has said.
The most recent Kantar data for supermarket sales of beef in the UK shows spend on beef to be up over 11% year-on-year, with volumes holding firm.
With tighter supplies of cattle in the UK, market prices have risen by 7p per kg in the past week.
EU young bull prices have strengthened and when combined with the UK price in the Bord Bia Prime Export Benchmark Price, a gap of 37c per kg has opened up with prices.
Despite the price increasing over the past few weeks, these increases are "not keeping pace with prices in our key markets and must move further and faster", IFA livestock chairman Brendan Golden said.
"Factories can and must do more on beef price to reflect the reality of the market conditions they are selling into," Mr Golden added.
