ב אִסוּר ” אוֹתוֹ וְאֶת בְּנוֹ” נוֹהֵג בִּנְקֵבוֹת, שֶׁזֶּה בְּנָהּ וַדַּאי; וְאִם נוֹדַע וַדַּאי שֶׁזֶּה הוּא אָבִיו, אֵין שׁוֹחֲטִין שְׁנֵיהֶם בְּיוֹם אֶחָד, וְאִם שָׁחַט אֵינוֹ לוֹקֶה, שֶׁהַדָּבָר סָפֵק אִם נוֹהֵג בִּזְכָרִים אוֹ אֵינוֹ נוֹהֵג.

The prohibition (to slaughter) “ the mother and its offspring” certainly applies to females, because when it comes to a mother we are always certain that it is her offspring.
And if it’s certain that it is known that its the father, we don’t slaughter them on the same day, and if its (the father) slaughtered (The slaughterer) he is not lashed, because there is a question if the prohibition applies to fathers as well, or only to mothers.
