The killing of cow for the guest had grown to such an extent that the guest came to be called ‘Go-ghna’ which means the killer of the cow. To avoid this slaughter of the cows the Ashvateyana Grahya Sutra (1.24.25) suggests that the cow should be let loose when the guest comes so as to escape the rule of etiquette. Thirdly, reference may be made to the ritual relating to disposal of the dead to counter the testimony of the Apastamba Dharma Sutra. The Sutra says102:– 1. He should then put the following (sacrificial) implements (on the dead body)

From the above passage quoted from the Ashvalayan Grahya Sutra it is clear that among the ancient Indo-Aryans when a person died, an animal had to be killed and the parts of the animal were placed on the appropriate parts of the dead body before the dead body was burned.

That the Hindus at one time did kill cows and did eat beef is proved abundantly by the description of the Yajnas given in the Buddhist Sutras which relate to periods much later than the Vedas and the Brahmanas. The scale on which the slaughter of cows and animals took place was collosal. It is not possible to give a total of such slaughter on all accounts committed by the Brahmins in the name of religion. Some idea of the extent of this slaughter can however be had from references to it in the Buddhist literature.
As an illustration reference may be made to the Kutadanta Sutta in which Buddha preached against the performance of animal sacrifices to Brahmin Kutadanta. Buddha, though speaking in a tone of sarcastic travesty, gives a good idea of the practices and rituals of the Vedic sacrifices when he said: “And further, O Brahmin, at that sacrifice neither were any oxen slain, neither goats, nor fowls, nor fatted pigs, nor were any kind of living creatures put to death. No trees were cut down to be used as posts, no Darbha grasses mown to stress around the sacrificial spot. And the slaves and messengers and workmen there employed were driven neither by rods nor fear, nor carried on their work weeping with tears upon their faces.” Kutadanta on the other hand in thanking Buddha for his conversion gives an idea of the magnitude of the slaughter of animals which took place at such sacrifices when he says :- “I, even I betake myself to the venerable Gotama as my guide, to the Doctrine and the Order. May the venerable One accept me as a disciple, as one who, from this day forth, as long as life endures, has taken him as his guide. And I myself, 0, Gotama, will have the seven hundred bulls, and the seven hundred steers, and the seven hundred heifers, and the seven hundred goats, and the seven hundred rams set free. To them I grant their life. Let them eat grass and drink fresh water and may cool breezes waft around them.”

In the Samyuta Nikaya (111,1-9) we have another description of a Yajna performed by Pasenadi, king of Kosala. It is said that five hundred bulls, five hundred calves and many heifers, goats and rams were led to the pillar to be sacrificed.
