Fetal pigs are the by-product of the meat packing industry and their large size makes them a good choice for study. They also allow for the study of fetal circulation, which differs considerably from that of an adult.
The size of the fetal pig depends on the age it was allowed for the mother to gestate:
|40 mm||56 days|
|80 mm||68 days|
|100 mm||75 days|
|158 mm||86 days|
|220 mm||100 days|
|300 mm||114 days|
Sometimes, fetal pigs are preserved in formaldehyde, a carcinogenic substance. They can be ordered for a little over $25 at biological product companies with preservatives that cause less damage to the skin. Nevertheless, gloves and goggles should always be worn when dissecting a fetal pig.
