Milk is a dairy product that is in many food products, such as cheese and yoghurt. It comes from dairy cattle (dairy cows), which are specific breeds of cattle that have been bred and farmed for their ability to produce large amounts of milk for human consumption. For the female cows to produce milk, they need to be continuously impregnated and sadly, for many dairy cows around the globe, life is far from dignified; being used and abused in farming systems. These animals are intelligent and fascinating! How much do you know about dairy cattle?
