Vietnamese Potbelly Pigs are considerably
smaller than standard American or European farm pigs, they weigh 43 to 136 kg
(100 to 300 lb). Boars become fertile at six months of age, long before they
are completely physically mature. Pot-bellied pigs are considered fully grown
by six years of age, when the epiphyseal plates in the long bones of the legs finally
close.
Because pot-bellied pigs are the same species as ordinary farmyard pigs
and wild boars, they are capable of interbreeding. Most pot-bellied pigs have
been crossed with various farm pig breeds.
Today, the Vietnamese and German governments have realized that the
indigenous Vietnamese pig subspecies exist only in mountainous Vietnam and
Thailand. The Vietnamese government has begun to subsidize local farmers who
continue to raise the indigenous pot-bellied pigs because it realizes they are
neither as prolific nor as large as other breeds.
