In the Bhagavad-gita, Lord Krishna 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 Krishna -- go-raksya -- is extremely meaningful. The whole world must learn from Krishna how to live happily without scarcity simply by producing food grains (annad bhavanti bhutani [Bg. 3.14]) and giving protection to the cows (goraksya). Krsi-go-raksya-vanijyam vaisya-karma svabhavajam [Bg. 18.44]. Those who belong to the vaishya community of human society, namely the mercantile people, must keep land for producing food grains and giving protection to cows. In the matter of protecting the cows, the meat-eaters will protest, but in answer to them we may say that since Krishna gives stress to cow protection.
Benefits of Cow Protection:
There are so many facilities afforded by cow protection, but people have forgotten these arts. The importance of protecting cows is therefore stressed by Krishna in Bhagavad-gita (krsi-go-raksya-vanijyam vaisya-karma svabhavajam [Bg. 18.44]). Even now in the Indian villages surrounding Vrndavana, the villagers live happily simply by giving protection to the cow. They keep cow dung very carefully and dry it to use as fuel. They keep a sufficient stock of grains, and because of giving protection to the cows, they have sufficient milk and milk products to solve all economic problems. Simply by giving protection to the cow, the villagers live so peacefully. Even the urine and stool of cows have medicinal value.
In our humble attempts in this direction we are encouraging masses to save the cows by encouraging them to participate in 'Gau - Grass' programme under which they may reserve a part of their income (for feed and construction in goshalas) on daily basis. After a month they can visit a goshala and use the donations for serving Gau Mata.
Also we are providing, some nice cow products from the indegeneous Indian cows for the welfare of both people and cows. The donations for these products are again used in serving Gau Mata.
