Prairie Malt Limited, a Canadian producer of malt for beer brewers, said on Thursday that it will reduce production and lay off 35 workers by the end of 2011, due to the end of a supply deal with a major customer.

The plant at Biggar, Saskatchewan is a joint venture of Cargill Ltd [CARGIL.UL] and Viterra Inc (VT.TO), two of Canada’s biggest grain handlers.
