evidence: The price for New Zealand's key dairy export, whole milk powder, may drop further at next week's GlobalDairyTrade auction as the country starts to ramp up production amid a global glut in milk supply. [...] Weak dairy prices have prompted analysts to pull back their expectations for Fonterra Cooperative Group's payout to farmers this season, with most forecasts now sitting below the dairy exporter's $5.25 per kilogram of milk solids. Market expectations range between $4.50/kgMS and $5.40/kgMS.
