Reference for Bekhorot 5:1

כָּל פְּסוּלֵי הַמֻּקְדָּשִׁין (הֲנָאָתָן לַהֶקְדֵּשׁ), נִמְכָּרִין בָּאִטְלִיז (וְנִשְׁחָטִין בָּאִטְלִיז) וְנִשְׁקָלִין בְּלִטְרָא, חוּץ מִן הַבְּכוֹר וּמִן הַמַּעֲשֵׂר, שֶׁהֲנָיָתָן לַבְּעָלִים. פְּסוּלֵי הַמֻּקְדָּשִׁין הֲנָיָתָן לַהֶקְדֵּשׁ. וְשׁוֹקְלִין מָנֶה כְנֶגֶד מָנֶה בַּבְּכוֹר:

All disqualified sanctified animals may be sold in the butcher shop, (slaughtered in the butcher shop,) and weighed against standard weights, except for the firstborn and the tithe, for their benefit [goes] to their owners. The benefit of disqualified sanctified animals goes to the Temple. Regarding a firstborn, we weigh a portion against a [non-sacred] portion.
