Vishnupurana 1.5.9

1.5.9

The divine Brahmá, influenced by their material energies, having created these beings, made others of his own will. Birds he formed from his vital vigour; sheep from his breast; goats from his mouth; kine from his belly and sides; and horses, elephants, Sarabhas, Gayals, deer, camels, mules, antelopes, and other animals, from his feet: whilst from the hairs of his body sprang herbs, roots, and fruits.
