In Vedic society, the economy was based on agriculture and cow protection. Sri Krishna mentions this in the Bhagavad-gita:
krsi-go-raksya-vanijyam vaisya-karma svabhava-jam (Bg 18.44) Five thousand years ago, when Krishna was personally present on this planet, there was enough milk, butter and curd. When there were festivals, the cowherd men would throw yogurt, milk, clarified butter and water upon the bodies of one another.
Everyone had sufficient stock of milk and other milk-products. Sri Krishna is glorified as the protector of the cows and brahminical culture (go-brahmana-hitaya ca).
The Brahma Samhita describes Lord Krishna to be tending the surabhi cows in His spiritual abode of Goloka Vrindavana, which is surrounded by millions of desire-fulfilling trees.
The cows are bathed every day. They are allowed to roam around freely in the farm so that they can stretch their limbs and get some exercise. Many visitors have commented that the cows are peaceful and content.
