Senegal dairy genetics project: Work package 2 update

  1. 1. Senegal Dairy Genetics project: Work package 2 update Karen Marshall FoodAfrica annual workshop, Kampala, Uganda 27-28 January 2014
  2. 2. Work package partners & objectives ILRI, EISMV, HU, MTT, project farmers To identify and promote utilisation of the most appropriate dairy breedtypes for more productive and profitable dairy enterprises in selected production systems in Senegal
  3. 3. Major activities 2013 1. Breed comparison     Socio-economic study: gendered Major field component, 18 month monitoring Breed-type determined through genetic analysis 2 sites: region of Thies and department of Mbacké (Touba) 2. Analysis of policies on dairy, particularly germplasm production and delivery systems 3. Capacity building
  4. 4. Breed comparison: project sites
  5. 5. Breed comparison: initiation Field staff recruitment: 2 female and 4 male, mobilised by motorbikes (due to cultural / religious reasons could not place female staff at Touba) Project sensitization in sites Survey to identify suitable dairy households: 623 households surveyed,288 identified as suitable (difficult to locate households as no complete list; lower number of cross-breeds than expected) Recruitment of 259 dairy households into project: individual visits plus small group workshops; given project leaflet and signed consent Project launch events (n=3): 135 male and 74 female participants, as individual dairy farmers and 11 organisations Activities January to April 2013
  6. 6. Project field staff Thies site Touba site Célestin Muyeneza (MSc in animal production, University of Dakar) Mamadou Lo (Doctor of Veterinary Medicine, University of Dakar) Ndeye Racky Ndiaye Elhadji Sow (MSc in population genetics, University of Dakar) (final year DVM, University of Da Mame Diara Ndiaye Sene Moudou (Doctor of Veterinary Medicine, University of Dakar) (Diploma of Livestock Production, CNFTEIA, St Louis)
  7. 7. Farmer sensitisation activities
  8. 8. Project launch events National & site level launch at Thies Ministers representative Site level launch at Touba
  9. 9. Breed comparison: socio-economic data Baseline survey: two survey tools – household head and adult female (259 households) (due to religious reasons unable to interview females in some households) Longitudinal survey round 1: socio-economic + individual animal data; animals ear-tagged; each staff attached to ~40 households (virtual ear tags used when farmers did not allow tagging; ‘transhumant’ survey developed) Longitudinal survey round 2: socio-economic + milk yield. Farmers trained in use of recording sheets and milk measuring (procurement difficulties for field equipment, esp. milk jugs) Longitudinal survey round 3: socio-economic + milk yield (241 households) (implemented automated animal identification system in database; recapture of missing / incorrect data) Activities April to December 2013
  10. 10. Ear tags Project animals number 3100 with 670 lactating females, 105 different breed-types (Dec 2013)
  11. 11. Field staff working with project dairy farmers
  12. 12. Type of information collected on dairy households Costs • Labour • Feed + water • Health-care • Housing • Mating • Marketing • Replacement animals • Equipment • Co-operative fees Benefits Animal & herd level • Milk & milk products: sold or consumed • Manure • Sale of dairy animals • Sale of sire services • Animal information: breed, age, parity, la st calving date, mating date, pregnancy status, date of birth, dry-off date • Milk records • Entries into herd: births, purchase etc. • Exits from herd: deaths, sale etc. Continual recording for 18 month+ period
  13. 13. Example survey table Gendered information on all costs + benefits
  14. 14. Milk measuring
  15. 15. Breed comparison: other data Body condition score: collected on all lactating females in selected survey rounds Milk quality (protein and fat): obtained on 310 animals using field-based milk analyser Body weights and body measurements Hair samples for DNA analysis and subsequent breed composition: first 104 samples genotyped Activities June to December 2013
  16. 16. Milk quality
  17. 17. Weights and body measurements
  18. 18. … but not always so easy
  19. 19. DNA samples
  20. 20. Preliminary SNP analysis results 104 animals: clusters represent the different breed-types
  21. 21. Management of field data Data mana Data collation, data checking, back-up MySQL database Each field staff enters own survey data into CSPRO data entry interface Project database manager, in Senegal Recollection of missing / erroneous data Farmer reports User access
  22. 22. Policy analysis  Generated via desk-top review combined with key informant interviews (in progress)
  23. 23. Capacity building: project farmers Use of recording sheets, milk measurements Domestic biogas, with Heifer International Senegal  9 training events  146 female and 366 male farmers Farmer biogas training
  24. 24. Capacity building: field staff Survey implementation + data -entry  4 training events of 5 days  Trained by ILRI and EISMV staff Professor Missohou from EISMV supporting training of field staff
  25. 25. Capacity building: students Program Country Gender PhD Cameroon Male PhD (attachment) Nigeria Female Masters Benin Male Masters Finland Female DMV thesis component Senegal Male
  26. 26. Main challenges 2013  Unable to establish ILRI hosting arrangement in Senegal  High number of project activities (to compensate for time lost due to project relocation)  Large volume of project data … but excellent project team (n=23) & project partner relations
  27. 27. 2014 work-plan  Completion of field-work (longitudinal surveys + DNA sampling)  Analysis of survey data  Household clustering  Breed assignment to individual animals + clustering  Estimate of cost & benefits for each breed x household cluster (dependant on group size)  Socio-economic breed comparison  Further farmer trainings combined with feedback workshops  Policy and value-chain analysis  Support to project students  Additional activities e.g. aflatoxin & brucellosis testing, feed analysis
