CryoStore aims to create a lasting research and education network for a new generation of animal husbandry experts with a broad, multidisciplinary approach to the complexity of modern animal production and the conservation of farm animal biodiversity, taking into account economic, societal and environmental needs. A vibrant and effective animal breeding and production industry is essential to meet Europe´s increasing need for sustainable and secure food production. Farm animal and fish breeding are global, highly competitive and knowledge intensive sectors, and currently European breeding organisations are global leaders. If Europe is to maintain its competitive advantage in these strategically important industries innovative research is needed in those reproductive technologies that underpin efficient and profitable animal production. As such, CryoStore will develop innovative technologies for improved cryopreservation of germplasm (gametes, embryos, germ cells) for use in assisted reproductive procedures, leading to increased reproductive efficiency in Europe´s livestock and aquaculture industries. Technological advances in germplasm cryopreservation will also be of key importance to future initiatives aimed at conserving Europe’s livestock biodiversity, through genetic resource banking. Conserving Europe´s numerous and diverse native breeds, many of which are seriously threatened, will be of crucial importance to future sustainable animal production as genetic biodiversity allows the expression of advantageous traits influencing adaptability to harsh environments or disease resistance. It is likely that selecting for naturally occurring traits will help overcome future difficulties in livestock production wrought by climate change. The intensive training of CryoStore ESRs in a wide range of scientific and transferable skills will greatly enhance their future employability in Europe´s important animal production industries and conservation initiatives.
