  • 1. Dairy Genetics East AfricaProject Objectives & Sites
    Presented by Okeyo Mwai(ILRI)
    at the Launch of the Dairy Genetics East Africa ProjectILRI campus, Nairobi, 9 February 2011
  • 2. Problem Statement
    Although past & current dairy improvement programs have clear livelihood potential&integrated approach (i.e.linking to markets; improving management and improving genetics)
    Theylack clear genetic strategy!
    - default is often to upgrade to exotics
    Even when conditions are unsuitable!
    “no one-size-fits-all situations”
  • 3. Similar challenges but different “strategies”
  • 4. Different
    different genetics!
  • 5. Who among these is happier?
  • 6. Objectives
    Determine appropriate cattle genotypes for smallholder dairy farmers in Eastern Africa
    Develop partnership and business model to sustainably deliver the desired germplasm to smallholders
  • 7. The approach
    • Application of high density snp technology to determine breed composition of cows owned by small-holders
    • 8. Combine this with traditional and participatory appraisal of animal and farm performance
    • 9. Development of a partnership including a fully articulated business model ready to implement delivery of germplasm in a subsequent phase
  • Some facts:
    Huge interaction between genetics & environment
  • 10. Change genotype but don’t change management
  • 11. Change management but don’t change genetics
  • 12. Change management and genotype
  • 13. Change management and genotype
  • 14. Optimum genotype depends on environment
  • 15. Site Selection
    • Criteria for sites:
    • 16. Range of genotypes within sites: we need sites with a reasonable “mix” of breeds
    • 17. Agro ecological zones: sub-tropical through temperate AEZ
    • 18. Logistics (accessibility): Easier logistics and access = lower costs and faster implementation
    • 19. Relevant range of production levels and farming systems
  • 20. Thank you
