Synopsis (short abstract) Sufficient genetic variation in livestock populations is necessary both for adaptation to future changes in climate and consumer demand, and for continual genetic improvement of economically important traits. Unfortunately, the current trend is for reduced genetic variation, both within and across breeds. The latter occurs primarily through the loss of small, local breeds. Inferior production is a key driver for loss of small breeds, as they are replaced by high-output international transboundar y breeds. Selection to improve productivity of small local breeds is therefore critical for their long term survival. The objective of this paper is to review the technology options available for the genetic improvement of small local breeds and discuss their feasibility. Most technologies have been developed for the high-input breeds and consequently are more favorably applied in that context. Nevertheless, their application in local breeds is not precluded and can yield significant benefits, e specially when multiple technologies are applied in close collaboration with farmers and breeders. Breeding strategies that require cooperation and centralized decision-making, such as optimal contribution selection, may in fact be more easily implemented in small breeds.

    This publication contains the proceedings of the FAO Global Conference on Sustainable Livestock Transformation, which took place at FAO headquarters in Rome on 25-27 September 2023. The objective of the conference was to provide a neutral forum for FAO Members, producers, scientists, development agencies, policymakers, civil society and the private sector to engage in dialogue on innovations and pathways to efficiently produce more nutritious, safe and accessible animal sourced foods with a reduced environmental footprint and to contribute to vibrant local and diversified livestock systems that are more resilient to shocks and disruptions. The proceedings provide a record of the main highlights of the conference, including the opening plenary session where there were addresses by the FAO Director-General, two keynote speakers and nine participants in two high-level ministerial panels; four plenary sessions dedicated respectively to the themes of better production, better nutrition, better environment and better life, with summaries of presentations and facilitated discussions; and a final plenary session including statements from 12 participants in two high-level ministerial segments. The proceedings also include one chapter each dedicated to the Global Youth Dialogue on Sustainable Livestock Transformation; the reports of five side events and an FAO launch event which took place during the conference; and a summary of 12 success stories of sustainable livestock transformation that were showcased in an exhibition held during the conference.

    Genetic resources and genomics for adaptation of livestock to climate change 2015

    Animal genetic resources (AnGR) are critical for global food security and livelihoods. Livestock products have high densities of energy, protein, and other critical nutrients, which are particularly beneficial for infants and expectant mothers. Around a billion people rely directly on livestock for their livelihoods, many of which are among the rural poor (FAO, 2009). Demand for animal products is foreseen to increase significantly in the future while competition for resources will intensify, dictating that livestock systems must increase both productivity and efficiency. Maintaining sufficient diversity of AnGR is necessary to ensure adaptation potential in times of uncertainty. In the future, climate change is expected to be a major force testing resilience of global food production systems (Thornton et al., 2009; Renaudeau et al., 2012). Ensuring that livestock systems remain productive and efficient while maintaining their flexibility will be a major challenge. Adaptation to climate change is unlikely to be achieved with a single strategy (Hoffmann, 2010). Clearly, modifications will be needed in animals' housing, reproduction, nutrition, and health care. Genetic changes in the animals (both within and across species) will also play a role. Preparation for these transformations will require a significant research commitment and genomics will play a role in the genetic measures taken for adaptation of livestock to climate change.
