The price of raw milk sold to dairy product makers rose by ?5 per kg in October as imported cattle feed gets costlier amid the weakening yen.

In response, three major milk product makers ¡ª Meiji Co., Morinaga Milk Industry Co. and Megmilk Snow Brand ¡ª have raised the retail prices of their products by 1 to 4 percent.

¡°The milk industry has long been in an abnormal state of severe price competition,¡± said Masatoshi Uchihashi, director general of the Japan Dairy Council.
