not prohibited in Vedas

By nature's law, or the arrangement of the Supreme Personality of Godhead, one kind of living entity is eatable by other living entities. As mentioned herein, dvi-padam ca catus-padaḥ: the four-legged animals (catus-padaḥ), as well as food grains, are eatables for human beings (dvi-padam). These four-legged animals are those such as deer and goats, not cows, which are meant to be protected. Generally the men of the higher classes of society-the brahmanas, ksatriyas and vaisyas-do not eat meat. Sometimes ksatriyas go to the forest to kill animals like deer because they have to learn the art of killing, and sometimes they eat the animals also. Sūdras, too, eat animals such as goats. Cows, however, are never meant to be killed or eaten by human beings. In every sastra, cow killing is vehemently condemned. Indeed, one who kills a cow must suffer for as many years as there are hairs on the body of a cow. Manu-samhita says, pravrttir esa bhūtanam nivrttis tu maha-phala: we have many tendencies in this material world, but in human life one is meant to learn how to curb those tendencies. Those who desire to eat meat may satisfy the demands of their tongues by eating lower animals, but they should never kill cows, who are actually accepted as the mothers of human society because they supply milk. The sastra especially recommends, krsi-goraksya: the vaisya section of humanity should arrange for the food of the entire society through agricultural activities and should give full protection to the cows, which are the most useful animals because they supply milk to human society.    (More...)

Jamadagni was more powerful than Kartaviryarjuna because of performing the agnihotra-yajna with clarified butter received from the kamadhenu. Not everyone can be expected to possess such a cow. Nonetheless, an ordinary man may possess an ordinary cow, give protection to this animal, take sufficient milk from it, and engage the milk to produce butter and clarified ghee, especially for performing the agnihotra-yajna. This is possible for everyone. Thus we find that in Bhagavad-gita Lord Krsna advises go-raksya, the protection of cows. This is essential because if cows are cared for properly they will surely supply sufficient milk. We have practical experience in America that in our various ISKCON farms we are giving proper protection to the cows and receiving more than enough milk. In other farms the cows do not deliver as much milk as in our farms; because our cows know very well that we are not going to kill them, they are happy, and they give ample milk. Therefore this instruction given by Lord Krsna-go-raksya-is extremely meaningful. The whole world must learn from Krsna how to live happily without scarcity simply by producing food grains (annad bhavanti bhūtani) and giving protection to the cows (go-raksya). Krsi-goraksya-vanijyam vaisya-karma svabhavajam. Those who belong to the third level of human society, namely the mercantile people, must keep land for producing food grains and giving protection to cows. This is the injunction of Bhagavad-gita. In the matter of protecting the cows, the meat-eaters will protest, but in answer to them we may say that since Krsna gives stress to cow protection, those who are inclined to eat meat may eat the flesh of unimportant animals like hogs, dogs, goats and sheep, but they should not touch the life of the cows, for this is destructive to the spiritual advancement of human society.    (More...)

Here we find some indication how the government can arrange for the eating of cow flesh. It is here indicated that in a rare circumstance when there is no supply of grains, the government may sanction the eating of meat. However, when there is sufficient food, the government should not allow the eating of cow's flesh just to satisfy the fastidious tongue. In other words, in rare circumstances, when people are suffering for want of grains, meat-eating or flesh-eating can be allowed, but not otherwise. The maintenance of slaughterhouses for the satisfaction of the tongue and the killing of animals unnecessarily should never be sanctioned by a government.    (More...)
