[If] one slaughters a bechor and sells it, and it becomes known that he did not show it [to an expert], what they ate, they ate, and he must return their money to them; and whatever meat they did not eat must be buried, and he must return the money to them. Similarly, [if] one slaughters a cow and sells it, and it becomes known that it was a tereifah, what they ate, they ate, and [he] must return the money to them; and whatever meat they did not eat they return to him, and he must return the money to them. [If] they sold it to non-Jews or gave it to dogs, they must pay him [only] the worth of a tereifah.

On account of the following blemishes a bechor may be slaughtered: Its ear is notched in the cartilage, not in the skin; [or] it is slit, although nothing is missing; [or] it has a hole as big as a vetch; or it has dried up. What is considered dried up? Anything that, if punctured, does not emit a drop of blood. R’ Yose ben Meshullam says: It is so dry that it crumbles.
