It will be difficult to give an exact figure for the total number of cows in the world. There's an estimate of over 1.5 billion cows grazing, sleeping, and chewing their cud at any given timein our world today. The country with the largest of cows is India, which is home to over 330 million cows.
It is closely followed by Brazil with 210 million cows and China with over a 100 million cows. Roughly 63% of the world's cattle are in India, Brazil & China. Hope you find this information useful.
