LONDON -- A minuscule cow with a taste for contemporary music has been named the world's smallest by the Guinness World Records book.

Guinness said Thursday the sheep-sized bovine from the West Yorkshire region of northern England measures roughly 33 inches from hind to foot.

The 11-year-old cow is named Swallow and her owner, Caroline Ryder, said she would spend the day either grazing with her herd or listening to BBC radio in her cowshed.

Swallow is a Dexter cow, a breed known for its diminutive stature, but is small even by Dexter standards.

She already has nine regular-sized calves and is pregnant with her 10th. Guinness said her youngest calf has already grown larger than she is.

Guinness World Records 2011 was published Thursday in the U.K.
