Manusmriti
यज्ञार्थं पशवः सृष्टाः स्वयमेव स्वयम्भुवा । यज्ञोऽस्य भूत्यै सर्वस्य तस्माद् यज्ञे वधोऽवधः ॥ ३९ ॥
Svayambhu (the Self-existent) himself created animals for the sake of sacrifices; sacrifices (have been instituted) for the good of this whole (world); hence the slaughtering (of beasts) for sacrifices is not slaughtering (in the ordinary sense of the word).
