Breeds of livestock on British farms are changing constantly. New breeds emerge, foreign breeds are imported, while some native breeds lose popularity and become endangered. More than half the native breeds in Britain are rare and potentially threatened with extinction, yet they are an integral part of our history and heritage. Many of them are distinctive animals, and some possess special characteristics that could be of value to the livestock industry. A return to more traditional values was seen towards the end of the twentieth century, and this will serve to enhance the value of native breeds.

Since the middle of the twentieth century the world has witnessed a succession of political and social disruptions. Globalisation, technological advancement, climate change, human migration, war and conflict - all have caused major worldwide upheavals. In this light, it's unsurprising that conservation of rare breed animals has been neglected. Yet the preservation of these genetic resources - this biological diversity - is an essential ingredient of sustainable life on Earth, and not something we can afford to lose. This book challenges often repeated 'facts' about livestock farming, straight from the horse's mouth. In it, rare breeds expert Lawrence Alderson CBE argues for a reasoned and evidence-based approach from political and public circles. Correcting misconceptions as he goes, he recounts the creation and development of the rare breed conservation movement, addresses extinctions and genetic safe-guarding measures, and considers where we go from here. Challenged as we are by climate change, sustainability and feeding the world, perhaps it is these endangered animals that hold the answer - perhaps with them, we can adapt to our changing environment and see a way forward to a more certain future.
