Hays Converter cattle were developed by Senator Harry Hays
of Calgary, Canada in the mid 1970's. They are a mixture of Holstein, Hereford
and Brown Swiss.
Their Cows weigh about 1,250 to 1,500 pounds at maturity and
are generally black, with white markings, although red and white animals are
not uncommon. They are hardy cattle adapted to range conditions in Western
Canada with good feet and legs, and nice udder conformation. They are also
known for their fertility, excellent milk production, and early sexual
maturity.
Hays Converters are the only registered pure-bred cattle
developed in Canada and are marketed throughout North America.
