How many horses, ponies, donkeys and mules are there in the EU? Where are they? What are they used for, and how are they kept?. These questions may sound simple - but until recently, they remained unanswered. Many European equines and large parts of the EU's equine sector were simply invisible to Europe's policy-makers - meaning that animal welfare and health policy and legislation could not take account of these animals' needs.
