Torah Temima points to Toras Kohanim / Zevachim on gender and temimut of shelamim.
E-Daf / Tsurras Hadaf
PDF of the daf / source
English: Whether male or female, he shall offer it unblemished.
Explicit permission for either gender — unlike the olah of the herd, which is male only.
A shelamim from cattle may be male or female, but must be tamim (without blemish). This is a major practical difference from the olah.
