הלכה על מנחות 112:11

That we not place a blemish upon consecrated animals: - That we not place a blemish upon consecrated animals; meaning to say that we not make any wound or any fracture upon a beast that is consecrated for the altar that disqualifies it as an offering - as it is stated (Leviticus 22:21), "and no blemish shall be upon it." And they, may their memory be blessed, said (Menachot 56b), "Read it as 'shall not be made in it.'" And the language of Sifra, Emor, Section 7:9 is, "'No blemish shall be upon it' - do not place a blemish upon it."
