Why goats ?• Goats are climate-smart and resilient livestock especially important to women and children• They are low hanging fruit for genetic improvement – rapid gains can be made with simple interventions• They are a low-cost model of other ruminantsSurrogate Sires to drive genetic gains in goats for improved livelihoods in a changing climate Steve Kemp, Nakami Wilkister, Triza Tonui, Christine Muhonja, Moses Ogugo, Julie Ojango, Jon Oatley, Christian TiamboE-mail: s.kemp@cgiar.orgBut• Poor genetic potential of existing populations means less milk and meat, and slow growth• With correspondingly high adverse environmental impact of unproductive animals• Genetic improvement can achieve rapid gains, but there is no no infrastructure to enable thisDonor ‘elite’ buckSpermatogonial stem cell (SSC) cultureSSC transplanted into an unlimited number of NANOS2 knockout recipient malesNatural heat detection & mating yields the productive & resilient offspring desired by communities, with the added benefit of reduced environmental impactSurrogate sires distributed as living AI straws, heat detectors & inseminatorsDelivery via Community Breeding schemes• Focus on the most valuable assets in communities- their livestock• Integrate indigenous knowledge and values in planned interventions• Expand networks for services and market opportunities for animal offtake• Ensure Farmer to farmer learning, and introduce options for stratification in livestock production systemsSurrogate Sires amplify the genetic potential of suitable males, while replacing the fragile, expensive & time-critical steps needed for delivery
