The optimism present at the Moorepark Open Day on Tuesday was tempered by the fact that it was another tough day at the Global Dairy Trade (GDT) with the index falling by 3.3%. Skim and butter were the big casualties, continuing the trend from recent weeks. Skim milk powder (SMP) fell in value by 6% while butter fell in value by 10.3%. It was a similar story on the European spot market with butter dropping in price by €95/t and SMP dropping in price by €60/t.
