Icelandic cattle are a breed of cattle native to Iceland.
Cattle originally came to Iceland with settlers around 1000 AD.[1] Icelandic cows are an especially colorful breed.
Icelandic cows have been genetically isolated for centuries, but are most closely related to a breed in Norway called Blacksided Trender and Nordland Cattle.
They are have been protected by strict disease-prevention measures.
According to the Agricultural University of Iceland, it would be more cost-effective to replace Icelandic cows with Swedish cows.
However, some have argued that Icelandic Cows are part of Iceland's cultural heritage and should not be replaced.
