We are often asked about breed qualifications of the 4
breeds of the National Swine Registry. Below is a summary of breed requirements
and markings.
Durocs
Durocs should be red with down ears. If a Duroc has white on
any part of its body, including its feet, it may be disqualified. It is okay
for Durocs to have white on the end of their nose, as long as it doesn’t break
the rim of the nose. They are not allowed to have more than 3 black spots and
none over 2 inches in diameter on the body.

Hampshires
Hampshires should be black with a white belt that goes
completely around both front legs and feet. They are allowed to have some white
on their nose, as long as it doesn’t exceed the rim of the nose. If the white
goes under the pig’s chin, it cannot be more than what a U.S. minted quarter
will cover. Hampshires can have white on their back legs, as long as it is only
from the hock down. These color requirements must be met by Hampshire boars and
gilts for them to be eligible to show in breeding events. If a Hampshire
doesn’t have a full belt, it can still be bred and its offspring can be
registered; however, it can’t be exhibited as a breeding animal at NSR shows.
Landrace
Landrace should be white with down ears and should not have
colored hair on any part of their body. If a Landrace has large, colored spots
or numerous colored spots on its skin, it is ineligible to be recorded.
Yorkshires
Yorkshires should be white with erect ears and not have any
colored spots larger than an U.S. minted quarter.
Please keep in mind if any breed shows evidence of a third
dewclaw, it is ineligible to be recorded.
Durocs, Landrace, and Yorkshires should have at least a 6-6 underline to
be recorded. Hampshires must have a
6-6 underline to be shown as a breeding animal, but can still be recorded if
their underline is not 6-6.
I hope this helps clear up any uncertainties you may have.
As always, let us know if you have any questions!
