SB 4.18.12
iti priyam hitam vakyam
bhuva adaya bhupatih
vatsam krtva manum panav
aduhat sakalausadhih
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After hearing the auspicious and pleasing words of the planet earth, the King accepted them. He then transformed Svayambhuva Manu into a calf and milked all the herbs and grains from the earth in the form of a cow, keeping them in his cupped hands.
