Leviticus 22:21, 23

And whoever offers a sacrifice of a peace offering to the LORD, to fulfill his vow, or a freewill offering from the cattle or the sheep, it must be perfect to be accepted; there shall be no defect in it.

Either a bull or a lamb that has any limb too long or too short you may offer as a freewill offering, but for a vow it shall not be accepted.
