Pioneering Stockfeed Innovation in Australia since 1923

Castlegate James is Australasia’s largest innovative supplier of high performance specialty co-product stockfeeds.



Castlegate James dates back to the foundation of UK grain merchant James & Son and Victoria Grains Stores in 1923, with both companies selling brewers grains to dairy farmers. James & Son Australia, James & Son New Zealand and Castlegate VGS merged in 2010 to create Castlegate James. Today, Castlegate James is a strong strategic partnership drawing on historical industry experience to provide famers with innovative, ‘value adding’ stockfeed options.
