The firm, which owns Scotbeef and Vivers Scotlamb, has seen the increase thanks in part to a new purpose-built retail packing facility at Queenslie in Glasgow and after acquiring G.D.Vivers.
Directors said Vivers had added £11.9m in sales in the time it had been part of the group while turnover from the existing Scotbeef business was up 19% at £142m.
Group finance director Alan Hill said the business was still growing but acknowledged margins were coming under significant pressure.
J.W.Galloway more than doubled its meat exports into Europe in the last financial year to £28.3m from £13.7m. Hill said exports in the current year were still showing growth, with both Scotbeef and Vivers shipping beef and lamb in increasing quantities into Italy, the Benelux countries and France.
