5.5.1.10

atha ya eṣa vaiśvadevaścarurbhavati | tasya pṛṣangaurdakṣiṇā bhūmā vā etadrūpāṇāṃ yatpṛṣato gorviśo vai viśve devā bhūmā vai viṭtasmātpṛṣangaurdakṣiṇā taṃ hotre dadāti hotā hi bhūmā tasmāttaṃ hotre dadāti

And what pap there is for the All-gods, the fee for that is a piebald bullock; for abundance of forms (marks) there is in such a piebald bullock, and the Visve Devâh are the clans, and the clans mean abundance: therefore a piebald bullock is the fee. He gives it to the Hotri, for the Hotri means abundance: therefore he gives it to the Hotri.
