evidence: Fonterra has lifted its milk price forecast for this season, thanks to rising global dairy prices. The mid-point is up 30 cents to $7.80 a kilogram of milk solids, while the forecast range for this season is now $7.30-$8.30 per kg of milk solids, up from $7-$8. Fonterra chief executive MIles Hurrell said the lift in the Farmgate Milk Price came off the back of five strong Global Dairy Trade (GDT) events.
