As an agricultural product, dairy milk is collected from farm animals. In 2011, dairy farms produced around 730 million tonnes (800 million short tons) of milk[4] from 260 million dairy cows.[5] India is the world's largest producer of milk and the leading exporter of skimmed milk powder, but it exports few other milk products.[6][7] Because there is an ever-increasing demand for dairy products in India, it could eventually become a net importer of dairy products.[8] New Zealand, Germany, and the Netherlands are the largest exporters of milk products.[9] The US Centers for Disease Control and Prevention recommends that children over the age of 12 months should have two servings of dairy milk products a day.[10]
