According toAustralia's ABC News, 7-year-old Knickers, a Holstein Friesian, is double the weight of the average animal of its breed and more than a foot and a half taller.
A huge cow by the name of Knickers has taken the internet by storm.
"We never thought he would turn into a big knickers".
Much of that is down to Knickers' pure animal magnetism - other cattle tend to follow him around the paddocks in their hundreds. But he's very placid, not aggressive, just inquisitive'. "We have a high turnover of cattle, and he was lucky enough to stay behind".
Vets said steers grew to be far bigger than bulls because they were castrated young and don't go through the hormonal changes that stop bulls growing. Cattle are also becoming bigger and bigger as a result of selective breeding, whereby farmers choose to breed the biggest cows in order to maximise meat returns.
'He's our favourite and one of our best assets, he's part of the furniture now, ' he said.
Knickers the steer is too big to be made into burgers, so he's getting to live out his days on the farm instead. But nobody - not even Knickers' owner in Western Australia - knows how he got so big, according to The Guardian.
Owner Geoff Pearson said that Knickers' sheer size saved him from the abattoir.
The world's largest steer is an ox named Bellino, who measured only about 3 inches taller than Knickers at a 2010 cattle show in Rome.
