The price of a cow depends on where that cow comes from and how the dairy market is doing. The location of the purchase makes a difference because some areas have cows overcrowding the farms while other areas do not have a good supply of cows. There is also a price difference depending on whether the cow has been fed with organic or generic food. Are you planning on buying a cow? You should go visit a few farms and compare prices before you decide on the one you buy.
