Milk commodity prices rose slightly in the latest Fonterra Global Dairy Trade (GDT) online auction on Tuesday (15 December).

After signs of slowing New Zealand milk production, this was the second limited rise in a row, with the index up 1.9% compared with two weeks earlier when it rose 3.6%.

Butter and lactose saw the biggest increases, although volume overall was low, with less than 26,000 tonnes on offer and 24,888 tonnes of produce bought by 112 bidders.

This compares with 34,720 tonnes at the corresponding sale in 2014.
