Having an animal biobank This mechanism was quite unexpected and we network will strongly increase the quality of the learned a lot from studying this spontaneous management of the diverse collections, through mutation. It is not only a question of veterinary the sharing of expertise and the development of sciences, but a more general ambition to common protocols and procedures.

The Network will support Network of Biological Resources Centers for the scientific and socioeconomic valuation of Domestic Animals (CRB-Anim) project? collections of biological samples for domestic animals, and establish new links between In 2010, a call for national infrastructures in life BRCs to fully exploit the synergy between sciences was launched by the French National them.

What are some of the technological interest in animal genetics? developments that have facilitated this work? Why are BRCs and the research I have been conducting research in animal they conduct important?

The reasons for this are twofold, and encompass both biodiversity and biomedicine. In France, the Network of Biological Resource Centres for Domestic “CRB-Anim aims to save and characterise the Animals has been established with the twin aims of preserving the nation’s genetic diversity of 22 species of domestic animals, with a focus on endangered breeds and genetic biodiversity while improving genomics research in the area genomic tools to improve knowledge of these genetic resources, and possible applications around population rescue, diversification EARLY ALLUSIONS TO the idea that humans dates back from the 1990s, during which of animal productions, and identification of should preserve the biodiversity and genetic lines time she established a DNA bank as part of breed specific traits,” Tixier-Boichard expands. of animals can be found in passages of the Bible, AvianDiv, a European project dedicated to the “Furthermore, we hope to contribute to in which Noah builds an ark to carry two of every genetic diversity of chickens.

It is a sentiment that has gathered support of France’s first cryobanks and, following the Network will be useful for livestock breeding throughout the last several decades; a fact successful sequencing of the chicken genome with a complementary approach to on-farm reflected by the rise of biological resource centres in 2004, initiated collaborations with European management of genetic diversity, as well as for (BRCs), which have been created to safeguard colleagues to identify the genes responsible for unravelling the genetic determinism of specific animal genetics in the face of an uncertain future, morphological and plumage colour variation traits or diseases. and facilitate research aimed at better knowledge in chickens. “It was at this stage that I realised and management of this heritage. just how precious our samples were – both To achieve its aims, CRB-Anim draws on for genomics and for all livestock species,” the diverse expertise of the wide network BRCs are, in many ways, a cornerstone of she recalls. created by its eight project partners and their biotechnology.

The development of common protocols and policies, and the linking of BRCs within a network, would therefore have benefits for both the scientists who work within the centres and external stakeholders. BUILDING UP BRCS It was with this in mind that, in 2011, Dr Michèle Tixier-Boichard answered a call to set up national infrastructures in life sciences, launched by the French National Research Agency (ANR) as part of its ‘Investing for the Future’ programme. “I considered this to be the ideal opportunity to support the development of BRCs for livestock species,” she elaborates.
