הַשּׁוֹחֵט בְּדָבָר הַמְחֻבָּר לַקַּרְקַע, אוֹ לַגּוּף, כְּגוֹן צִפֹּרֶן וְשֵׁן הַמְחֻבָּרִים בִּבְהֵמָה, שְׁחִיטָתוֹ פְּסוּלָה. וּבְתָלוּשׁ מִן הַקַּרְקַע וּלְבַסוֹף חִבְּרוֹ בַּקַּרְקַע, לֹא יִשְׁחֹט, וְאִם שָׁחַט, שְׁחִיטָתוֹ כְּשֵׁרָה, וַאֲפִלּוּ אִם בִּטְּלוֹ, וְהוּא שֶׁלֹּא יְהֵא נִשְׁרָשׁ בָּאָרֶץ אַחַר שֶׁבִּטְּלוֹ.

If one slaughters with something connected to the ground, or a body, like a fingernail and a tooth connected to an animal, the slaughter is invalidated.
Or something detached from the ground but that will end up connected to the ground, we don’t slaughter, if one slaughters it is permitted, and even if it is nullified, as long as it is not rooted again after it is nullified.
