  • IntroductionIntroductionWhy is this research important for ILRI – I don’t now if the research is important for ILRI, and not research should be important for ILRI Who are the recipients of the outcomes: farmers in marginal systems are most likely to benefit.How will it change their lives: resilient, empower, profit.

    • 1. Unzipping the Goat Helix Harnessing genetic diversity to improve goat productivity in Africa M. Agaba, T. Dessie, J. Djomika, G. Gebreyessus, F. Meutcheye, S.Osama ILRI BioSciences Day, Nairobi, 27 November 2013
    • 2. Goat Opportunity: its significance CAT SHE GOA BUF
    • 3. Goat Opportunity: its significance
    • 4. The constraints • Weak institutional arrangements to exploit goat potential. • Unutilized Diversity to accelerate goats’ performance. • Inadequate capacity at al levels, especially expertise in breeding.
    • 5. Objectives • Characterize the genetic architecture of goat populations in Cameroon and Ethiopia with view to identifying DNA signature of adaptation. • Establish institutional and community arrangements that maximize the value derived from goat production. • Demonstrate the Utility of DNA tools in boosting productivity of goats under small holder farming systems goat productivity. • To build expertise of the next generation scientists/practitioners.
    • 6. Methods: Innovation Platform Solid Evidence, Suitable Technologies, Sound Policy abattoir Media IRAD Goat traders Gene sink (drive gene flow) PADPR ACEFA Farmer groups Gene Bank NGOs enabling Model to be cascaded Locally
    • 7. Methods: Innovation Platform Solid Evidence, Suitable Technologies, Sound Policy Production aspects Constraints and challenges Performances - Growth delay ( stunted animals) Low resistance to diseases Low productivity How and where to get improved animals? Husbandry/ management - Heat detection and management General reproduction management to avoid consanguinity Breeding buck management Need of fences to avoid animal’s rambling Formulation of supplementary feed - Few opportunities (market) Wide variation of prices Marketing -
    • 8. Methods: Gene discovery How do the goat genomes stand on the diverse African eco-geography? What the DNA attributes underlie adaptation? How can we use DNA tools to accelerate goat performance?
    • 9. Methods: Gene discovery Developing DNA testing for use in small holder systems
    • 10. Methods: Gene discovery Discovery and utilisation of high fecundity genes in African Goats GBS of Superdoes and controls on MiSeq. Genome which scan for possible novel goat fecundity loci Develop and validate a MAS DNA assay for high fecundity to test Bucks We R here Collet tissue specimen from 100 - 200 does with 3+ kids on more than 2 times from CAMEROON plus 100 does with 1 kid at a time for more than 3 times Mutation Detection in Fecundity candidate genes

    • 12. Conclusions and discussion points • IP is a useful mechanism to engage “policy” making, and technowledgy uptake. • Goats present a unique opportunity through which to realize the aspirations of young, old, in different agroecological zones. • It is feasible to use DNA tools to impact performance in the near term with the right trait e.g. reproductive efficiency • Goats (ruminants) are superoganisms, therefore studying rumen biota is essential.
    • 13. Where to from now? Keep working • Demonstrate utility of DNA science in breeding – small holders’ MAS. • Deepen exploration of Goat rumen microbiome function and diversity. • Broaden geographical scope of to include goat population in Sudan and Tanzania. • Strengthen interaction with the Relevant CRPs, and with NMAIST, NARS in SUDAN, Cameroon, Ethiopia and Tanzania.
