Reference for Chullin 5:1
אוֹתוֹ וְאֶת בְּנוֹ, נוֹהֵג בֵּין בָּאָרֶץ בֵּין בְּחוּצָה לָאָרֶץ, בִּפְנֵי הַבַּיִת וְשֶׁלֹּא בִפְנֵי הַבַּיִת, בְּחֻלִּין וּבְמֻקְדָּשִׁין. כֵּיצַד. הַשּׁוֹחֵט אוֹתוֹ וְאֶת בְּנוֹ חֻלִּין בַּחוּץ, שְׁנֵיהֶם כְּשֵׁרִים, וְהַשֵּׁנִי סוֹפֵג אֶת הָאַרְבָּעִים. קָדָשִׁים בַּחוּץ, הָרִאשׁוֹן חַיָּב כָּרֵת, וּשְׁנֵיהֶם פְּסוּלִים, וּשְׁנֵיהֶם סוֹפְגִים אֶת הָאַרְבָּעִים. חֻלִּין בִּפְנִים, שְׁנֵיהֶם פְּסוּלִים, וְהַשֵּׁנִי סוֹפֵג אֶת הָאַרְבָּעִים. קָדָשִׁים בִּפְנִים, הָרִאשׁוֹן כָּשֵׁר וּפָטוּר, וְהַשֵּׁנִי סוֹפֵג אֶת הָאַרְבָּעִים וּפָסוּל:
The prohibition against slaughtering an animal and its young on the same day (Lev. 22:28), is obligatory in the Holy Land, and out of it, during and after the existence of the Temple, with respect to animals slaughtered for profane use [i.e. to eat them], and to those slaughtered as consecrated sacrifices, as follows. When a person slaughtered an animal and its young [on the same day] without the temple-court [not as holy sacrifices, but] as animals slaughtered for profane use though both animals are Kosher, yet in slaughtering the second, he incurred the penalty of the forty stripes. Should he have slaughtered them outside the temple-court as holy sacrifices, he has incurred the penalty of utter excision [כרת] for the slaughter of the first. Both animals are Pasul, and he has moreover incurred the penalty of forty stripes for the slaughtering of each animal. Should he have slaughtered them as חולין [i.e. for profane or ordinary use] within the temple-court, both animals are Pasul; and for the slaughter of the second, he incurred the penalty of forty stripes. If both were consecrated sacrifices, and were slaughtered within the temple-court, the animal first slaughtered is a valid sacrifice, and the person who slaughtered it has not incurred any penalty for so doing; but he incurred the penalty of the forty stripes for the slaughter of the second animal, and that animal is unfit for sacrifice.
