Both an animal offered as a substitution as well as an animal set apart for sacrifice retain their consecration

'He shall not replace it or exchange it, a good for a bad, or a bad for a good; or if he does exchange animal for animal, then both it and its substitute shall become holy.

Hebrew

לֹא יַחֲלִיפֶנּוּ וְלֹא־יָמִיר אֹתוֹ טוֹב בְּרָע אוֹ־רַע בְּטוֹב וְאִם־הָמֵר יָמִיר בְּהֵמָה בִּבְהֵמָה וְהָיָה־הוּא וּתְמוּרָתוֹ יִהְיֶה־קֹּדֶשׁ׃ ‬

Greek
