Tanzania dairy genetics project: Identifying appropriate germplasm for smallholder dairy farmers Tanzania dairy genetics project: Identifying appropriate germplasm for smallholder dairy farmers Presentation Transcript

  • Tanzania dairy genetics project: Identifying appropriate germplasm for smallholder dairy farmers Dennis Mujibi (ILRI) Inception workshop of the AgriTT project: Evaluation of breed composition, productivity and fitness for smallholder dairy cattle in Tanzania, Dar es Salaam, 10-11 June 2014
  • Problem Statement  Several past & current dairy improvement programs have an integrated approach (i.e. Market development - MoreMilkIT; improving management and Feeding - EADD)  There is often no genetic strategy Most farmers want high producing animals thus continuously upgrade to higher exotic levels even where it is undesirable to do so.
  • Problem Statement 0 1 2 3 4 5 6 7 8 Yield(Ltr) Breed Types Average Test Day Milk Production in Major breeds YIELD 0 1000 2000 3000 4000 5000 Harsh Poor Good Production environment Yield(l) Indigenous X-bred Exotic Ideal: Designer genetics fit to specific smallholder production systems
  • Objectives  Characterization of current dairy cattle genotypes in use & the determination of the most appropriate genotypes for smallholder dairy farmers in Rungwe and Lushoto  Understanding of what dairy technologies are most desired (lacking) by smallholder dairy farmers in Rungwe and Lushoto
  • Approach Apply emerging NGS technologies to determine breed composition of dairy animals Correlate breed-type with performance data obtained through participatory appraisal, in-situ Listen to farmers…continuously and incorporate their concerns and views in design of on-going interventions
  • Project Study Sites  Selection Criteria On-going ‘Maziwa Zaidi’ Activities Emerging Dairy industries with high potential Range of breed types
  • Data requirements  Reproductive Performance  Breeding and Bull use pattern  Bio-samples and genotyping  Survival and mortality data  Milk yield, Sanitation and Quality data  Animal health/infertility data  Cost benefit analysis/Productivity Analysis  Dairy technology gaps and knowledge systems
  • Activities  Tissue and hair sampling: to be carried out during ear tagging  Longitudinal survey: Visit farmers every 2 months for 1 year  Performance recording: To be completed by farmer and enumerator during longitudinal study  Focus group discussion: At least 2 focus group discussions  ICT technologies to record farmer Knowledge, views and concerns
  • Data flow and processing Phenotypic data on animals from project farms Genomic data on animals from project farmsConnectivity via web and application platforms Feedback to support management decisions Individua l farmers Relation al Databas e Computin g Server Data capture, visualization and feedback platform* Analytical platform*
  • Capacity Development  Genetic diversity studies*  Cost benefit analysis*  Performance evaluation – 2 students  Programming: development of decision support and data visualization tools – 1 student  Programming: development of data collection and farmer feedback systems – 1 student  Relational database development – 1 student  Analytical platform development – 2 students
  • Performance recording is key to identification of appropriate genotypes Field Activities D G E A
  • Animal Selection/Feedback  Cow Selection In-calf or calved down within the last 3 months Breed diversity Minimal relationship between cows  At least 2 focus group discussions to provide feedback (Possible) Provision of extension materials on specific topics through Audio
