A price gap of almost 70p/kg exists on factory prices for fat lambs and hoggets processed on either side of the Irish Sea in 2024.From January to the end of July, official reports show factory prices have averaged 690.3p/kg in NI compared to 758.6p/kg paid by abattoirs in Britain. That price gap is worth just over £14 on a 21kg lamb carcase, although at its peak, the differential exceeded £30 on new season lambs.
