Reference for Bekhorot 81:52

ושנעבדה בו עבירה וכו':

And if the Divine Law had written [two restrictive texts], [I might have thought that] they only excluded the two cases where [the animals] are weak, but as regards an animal with an offensive smell or sight but which is not [physically] weak, I might have said that it was not so.
