The piglet is seen yawning or gasping for breath as it is held up to the camera.
It is unclear where the video originated from but it has been widely shared on Chinese social media.
Many viewers are now speculating about the reason behind the animal's deformity - with some blaming environmental pollution.
Last year, a farmer claimed he was inundated with cash offers after photos of a similar mutant pig belonging to him went viral .
Friends and neighbours of Tao Lu rushed to his property in Yanan township in the city of Nanning, China, after news of the deformed pig spread.
One of the last to be born in a litter of 19, the little piglet was described by witnesses as having a human face and a penis on its forhead.
And when a local newspaper published pictures of the bizarre-looking animal, several people contacted Tao, offering to buy it.
adly, the animal died after being rejected by its mother and refusing a bottle.
Tao, 40, said: "It was a large litter, and the mutant was one of the last of 19 piglets to be born.
