Short answers, pulled from the story.
Hereford cattle originate from Herefordshire in the West Midlands of England. Selective breeding began in the mid-eighteenth century, carried out by a small number of families in the county, predating the better-known work of Robert Bakewell.
In 2023, populations reported by 62 countries totalled over seven million head. Uruguay, Brazil, and Chile each reported populations of over 100,000.
The first Herefords reached the United States around 1817, brought to Kentucky by the politician Henry Clay. The modern American Hereford breed traces to a herd established in 1840 in Albany, New York.
A Polled Hereford is a hornless variant of the Hereford, carrying a natural genetic mutation that removes the horns. Iowa rancher Warren Gammon began selecting for this trait from 1889, founding the registry with 11 naturally polled cattle; the American Polled Hereford Association was formally established in 1910.
Hereford cattle are prone to ocular squamous cell carcinoma (eye cancer), particularly in sunny climates and among animals with low eye pigmentation. Other heritable concerns include vaginal prolapse and dwarfism, the latter caused by an autosomal recessive gene that affects heifers and bulls equally.
The Traditional Hereford is a strain kept separate from outside crossbreeding, preserving earlier characteristics such as hardiness and thriftiness. It is now recognised as a minority breed of value for genetic conservation.
