world biggest cows

This its the world's biggest 6ft cow. Chilli the giant bullock stands at 6ft 6ins and weighs well over a ton
Despite his grand stature, Chilli only grazes on grass during the day and enjoys the occasional swede as a treat.
The heifer, who is almost as high as he is long, lives at the Ferne Animal Sanctuary in Chard, Somerset, after he was left on their doorstep aged just six-days-old. Chilli dwarfs most horses, is the same height as a small elephant and casts a shadow over his cattle companions who are about 5ft in height
"He now stands at 6ft 6ins from the floor to the top of his shoulder and he is massive when he holds his head up.
"We have made an application to Guinness Book Of Records and we are quite confident he will get it."
Chilli, who is 6ft 7ins long, was left running around on the doorstep of the sanctuary along with his twin sister Jubilee in 1999.
Over the years, staff noticed Chilli begin to tower over his sister and companions. She continued: "We don't know what has made him so tall. He doesn't eat that much and his feet and head are in proportion - he is just very large.
"He is a very friendly and gentle cow so we hopes he manages to break the record - he deserves it."
At present, the tallest bovine in the world is 6ft 8ins Fiorino, who lives in Italy.
A spokeswoman for the Guinness Book Of Records said: "I can confirm that an application has been received for Chilli which is currently under research."
