Global dairy prices have risen to a two-and-a-half year high.
Prices rose by 3.5 percent overall at this morning's GlobalDairyTrade auction. That was the eighth increase in the past nine auctions.
The increase in supply has been helped by a tightening of supply.

That is the highest level for the whole milk powder category since June 2014.
The skim milk powder index rose by 1.4 percent to US$2,570/mt.
Cheddar rose by 2.2 percent to US$3,752/mt and butter increased by 1.7 percent to US$4,262/mt.
