The piglet was the thirteenth in a litter born on a farm in the rural Udon Thani province in northeast Thailand on April 27.
Locals believe the eight-legged still-born animal was sent to bring them good luck and fortune, and are flocking to worship the creature at the owner’s house where its corpse has been pickled in a jar.
Residents were pictured sitting cross-legged before the dead pig and praying while choosing their lottery numbers based on its features.
Owner Kanchana Supanich, 46, said 13 had been the most popular number – as the piglet, which was nicknamed Fat, was the 13th to be born to its mother.
The number 28 had also been a hit, because of the piglet’s two heads and eight legs – while 38 had also proved popular because of the animal’s three ears and eight legs.
Ms Supanich said: “The pig is lucky, I have never seen any animal born like this. It has eight legs, three ears and two heads.
“It is a male pig, but was not breathing when he was born. People are using the numbers to gamble. I’m sure he will bring the village good fortune.”
This is not the first time an eight-legged pig has been sighted.
In March, a Chilean farmer was shocked when his sow gave birth to a real-life spider pig with eight trotters and another piglet with two mouths.
The deformed piglet was born in the village of El Galpon, in the northwest Argentine province of Salta.
Owner Santiago Valdez described his astonishment at witnessing the birth of the eight-legged pig which has been christened “spider-pig,” referring to the character of the Simpsons movie.
It sadly died shortly after birth.
Mr Valdez said: “I have no idea why it happened. I was surprised that nobody has asked for it to carry out investigations.
“But nobody asked for it, so I just threw it away.”
He added he had not noticed any abnormality in the sow that was giving birth, although she had begun to produce less piglets.
Animal rights activists believe it is due to industrial chemicals that the farmers are said to have used on their land or possibly the side-effect of intensive farming techniques.
