English: “Male or female” — a definite male or a definite female, not a tumtum or an androgynous. And is this not a kal vachomer? If an olah, which may come from birds, may not come from a tumtum or androgynous — shelamim, which may not come from birds, how much more should they not come from a tumtum or androgynous!
In Sifra: Flock shelamim are stated separately from cattle because each class has distinct features (libation size, communal frequency). The “male or female” clause bars animals of indeterminate sex; the kal vachomer from olah reinforces the exclusion.
Type of Learning
Kal vachomer (olah birds → shelamim sex requirement).
What Is Learned
Shelamim from the flock must be a clearly sexed male or female; tumtum and androgynous animals are invalid even though shelamim already exclude birds.
