The following [defects] render cattle terefah: If the esophagus was pierced; If the windpipe severed; If the membrane of the brain was pierced; If the heart was pierced as far as its cavity thereof; If the spine was broken and the cord severed; If the liver was gone and none of it remained; If the lung was pierced, Or if part of it was missing. Rabbi Shimon says: only if it was pierced as far as the main bronchi; If the stomach, If the gall-bladder was pierced, If the intestines were pierced; If the innermost stomach was pierced, If the greater part of the outer stomach was pierced. Rabbi Judah says: in a large animal [if it was torn] to the extent of a handbreadth, and in a small animal the greater part. If the omasum (the third stomach of a ruminant) [was pierced]; Or if the second stomach was pierced on the outside; If the animal fell from the roof; If most of its ribs were fractured; Or if it was mauled by a wolf. Rabbi Judah says: small animals [are terefah] if mauled by a wolf, large cattle if mauled by a lion; small fowl if mauled by a hawk, large fowl if mauled by a falcon. This is the rule: if an animal with a similar defect could not continue to live, it is terefah.
