Factory agents are responding to tighter numbers in the market and are increasing prices in a bid to attract throughput. While agents are keen for stock, they are also trying to keep a lid on prices paid across the board and as such are targeting regular sellers and producers with significant numbers on hand.Prices for heifers have moved upwards by 5c/kg, with sellers who were last week trading at a base of €3.75/kg now securing €3.80/kg. Likewise those negotiating a base of €3.70/kg last week are now pushing for €3.75/kg. Demand for Angus-bred stock remains solid, with reports in the west and northwest of a flat price of €4.00/kg being paid. In other regions a flat price of €3.90/kg to €3.95/kg has been reported for mixed lots of Angus and Hereford stock.
