A cow sticks its head out of a pen as it waits for feed on a 40-hectare farm managed by New Zealand dairy export giant Fonterra Co-operative Group in Yutian County, Hebei Province around 150 km (93 miles) southeast of Beijing in this March 15, 2012 file photo. Global food and dairy companies are making another round of big bets on China's fast growing dairy sector, hoping to position themselves as safe alternatives even after a lethal baby formula scandal burned many of them the first time around. Fonterra, which sells $2 billion a year of imported milk products in China, is also building large dairy bases near Beijing, the milk from which it sells at a premium to other dairies.
