The 'livestock' term refers to animals domesticated for producing commodities for man such as food, fiber and draught. Livestock biodiversity is integral to our culture, history, environment, and economy. Thousands of livestock breeds have evolved over time to suit particular environments and farming systems. Conservation of these genetic resources relies on demographic characterization and correct breeding schemes. In addition, molecular genetic studies allow to identify and monitor the genetic diversity within and across breeds and to reconstruct their evolution history. The conservation of livestock variability is also a crucial element in order to preserve and valorise specific nutritional and nutraceutical properties of animal products. Efficient ex situ and in situ conservation strategies are obligatory tools in order to implement an appropriate action for the conservation of livestock biodiversity. The main issues concerning different species are summarised, with particular reference to'the livestock biodiversity still existing. Some examples of ex situ conservation strategies developed in Italy are presented, and the different actions in defense of Animal Genetic Resources (AnGR) developed within the European Community are illustrated.
