On 8-11 June 2009, the international symposium on Sustainable improvement of animal production and health took place in Vienna, Austria, organised by FAO and the International Atomic Energy Agency (IAEA). Proceedings of the symposium are now available on the web, edited by N.E. Odongo, M. Garcia and G.J. Viljoen. They contain the contributions to the plenary session and to five sessions that dealt respectively with: interactions among nutrition, reproduction and genotype; effects of nutrition, reproduction, genetics and environmental factors on animal productivity; transboundary, emerging and zoonotic diseases; one health; and achieving food safety and security in the 21st century. Several of the papers dealt directly or indirectly with the use of specific biotechnologies in livestock.
