How many pairs of ribs does a fetal pig have?
It depends on the breed of pig.
A fetal pig has as many ribs as an adult pig.
Over the years, the pig's anatomy has changed due to humans mating different breeds together.
In the past, pigs were shorter than they are now.
Generally, the longer a pig is from snout to tail, the more ribs it has.
An exceptionally long pig, like the American Landrace, can have 16 or 17 pairs of ribs.
Lacombe pigs might have 13 pairs or even fewer.
