Farmers in the Republic of Ireland received €118.72 less for a 280kg R3 grade heifer carcass compared to prices in Northern Ireland, figures show.
In the Republic of Ireland the R3 heifer price stood at 375.3c/kg in the week ending December 11, following an increase of 7.3c/kg from the same week in November, figures from the Livestock and Meat Commission show.
However, farmers in Northern Ireland were taking home 417.7c/kg on average for an R3 grade heifer in the week ending December 11, leaving the price difference between north and south at 42.4c/kg.
In the space of four weeks the R3 heifer price in Northern Ireland increased by 24.6c/kg.
The EU average price had increased by 4.2c/kg when compared to the corresponding week in November.
This meant that the R3 heifer price paid to farmers in the Republic of Ireland was 3.4c/kg below the EU average at the beginning of December.
The price difference between Northern Ireland and the EU average widened from 18.6c/kg in the week ending November 13, to 39.0c/kg at the start of this month.
Across the Irish Sea, farmers in Britain were getting a R3 heifer price of 426.9c/kg in the week ending December 11.

This would represent a difference in price of €25.76 and €144.48 on a 280kg R3 grade heifer carcass.
