According to Srila Sridhara Svami, Lord Sri Krishna instructed His father and other residents of Vrindavana in the technical details of this Vedic sacrifice to assure the quality of the sacrifice and also to inspire Nanda and the others with faith in the concept of such a sacrifice. Thus the Lord mentioned that there must be orthodox brahmanas, regular sacrificial fires and proper distribution of charity. And things were to be done in the order given by the Lord.
