At one point of time, the one who had more cow was considered rich. It was also used as money for trading. This was considered as social status in the society. Its similar to gold which we have now.
The real reason for worshipping the cow is because of its benefits. Only the Indian cow has got these benefits. India cow is also called as BOS INDICUS(indigenous cow). Some of its breeds are as follows:
If you see these cows they all have a hump behind their back. Ancient Rishi used to believe that on the hump of these cow there is a suryakethu nadi which makes its byproducts more nutritious and beneficial. The by products are milk, cow dung and urine. One more unique factor of the Bos indicus cow is that it gives A2 protein while other cows available in other parts of the world give A1 protein according to scientists research.
A2 Cows are very less, may be around 5% of worlds population. So most of you are drinking A1 milk. A1 protein can't be digested well, so there are lots of chances of getting the disease.
From A2 milk we can get B2, B3, B12, A vitamins. It has 8 types of protein, 25 types of minerals, 21 amino acids, phosphorous, glucose, carotene, iodine, etc. Cow dung contains elements like carbon, nitrogen and phosphorous.
