The record for production by a Jersey cow was set in 1892 by a cow named Lilly Flagg, who produced 1047 pounds and 3/4s ounce of butter and 11,339 pounds of milk over her lifetime!
Originally bred on the isle of Jersey, Jersey Cows Bos Tauros can be dated back to 1700 as a distinct breed. They tend to be smaller than many other breeds of cattle, weighing between 400 and 500kg on average when fully grown. They can also be recognised by their characteristic honey-brown colour and shiny black hooves, which are very tough. They are very resilient cattle, being able to thrive all over the world, where they are prized for their milk, which has up to 20% more protein and calcium, 25% more butter fat and a much higher concentration of vitamins and minerals than the milk of other breeds.
