AN AMBITIOUS pig farmer raising muscle-bound mutant porkers for the bacon market is selling their sperm on Facebook.

The Cambodian-based breeder is flogging the semen - along with insemination kits - to others looking to move into the 'Frankenswine' market.

Scientists in South Korea have been credited with originally genetically-engineering double-muscle hogs to avert a future pork shortage crisis.

They carefully altered pig genes to create super-sized swines capable of producing more meat than usual breeds.

Farmyard footage shows similar porky 'monsters' that look like they’ve been gorging on steroids or even pumping iron in the gym.

The shocking images have been condemned by animal lovers who say the burly pigs are the "stuff of nightmares."

Giant hogs were first developed at Seoul National University, in South Korea, by microbiologists on a mission to create more meat.

Jin-Soo Kim, who led the work, said: “We could do this through breeding. But then it would take decades.”

Years of cross-breeding has already created the enormous Belgian Blue cattle as featured by the Sun Online on Saturday.

But Kim’s team have by-passed this method and created the bulked-up pigs by tinkering with a “myostatin gene”.

This gene usually keeps the growth of muscle cells in check, but when it is altered this does not happen and the pig grows to more than twice its normal size.

The genetic editing also produces a higher muscle mass which means more meat is yielded and it also a lot less fatty.

Kim and his colleagues originally produced more than 30 piglets.

However, new images from a the farm in Banteay Meanchey, Cambodia shows the giant pig business is booming with pens packed full of porkers.

The farmer raising the pigs is even offering to sell the sperm to others looking to breed the giants.

He also shared video footage of the muscle-bound animals squealing as they fight over food.

Scientists insist the mutation is safe because rather than transplanting genetic information from one species to another they have simply edited genes.

However, at the moment no country allows its people to eat the genetically modified products.

The EU bans any importing of genetically modified food into member states amid fears for the safety and quality of the meat.

The UK Food Standards Agency said all genetically modified (GM) food has to undergo a rigorous safety assessment before it is permitted to be placed on the EU market.

Animal-lovers reacted with a mixture of horror and fury after viewing the images online.

One wrote: “This is grotesque! Obviously bred like this. Are there no laws to stop this sort of thing. Ugh!”

Another called the images “unbelievably disgusting”.

And a third commented: “What the f*** is this nightmare!!!!???”

Animal rights organisation Peta also blasted the “disturbing” images of the “double-muscled” animals.

PETA's Mimi Bekhechi told Sun Online: “Hulk-like pigs are the stuff of nightmares, not meals, and those who are genetically engineered are also likely to be born with painful health issues.

“When South Korean and Chinese scientists created 32 double-muscled piglets in 2015, only one was considered even marginally healthy.

“We urge anyone disturbed by the thought of eating manipulated and mutilated pig flesh to bypass the bacon.”
