The 101st prohibition is that we are forbidden from slaughtering an animal and her child on the same day. This applies both to sanctified and non-sanctified animals.
The source of this prohibition is G‑d's statement,1 "Do not slaughter an animal and her child on the same day."
One who transgressed this prohibition and slaughtered them is punished by lashes.
The details of this mitzvah are fully explained in the fifth chapter of tractate Chulin.
