2326 GMT - A local Chinese company called Junlebao is launching an A2-protein infant milk formula in the Chinese market, another challenge for New Zealand stock-market darling a2 Milk. Junlebao's milk is sourced from China, Citi says, meaning that Chinese dairy farms have possibly built a reliable A2-protein milk pool that could spur even more competition. "This could suggest that other domestic brands are close to launching A2-protein formulas, should they all use the same local milk source," Citi says. Milk products with only A2 proteins are advertised as being easier to digest. A2 Milk shares have fallen from about NZ$18/share in July to NZ$13/share in recent trade Tuesday
