  • 1. www.mtt.fi/foodafrica Senegal Dairy Genetics: Using advanced DNA approaches to determine breed composition The Senegal Dairy Genetics project is using advanced DNA approaches to determine the breed-type of dairy cattle in the absence of farmer recorded pedigree. In this way, Senegal dairy farmers and other stakeholders in Senegal dairy are benefiting from the genomics revolution This poster is part of the FoodAfrica Programme, financed as a research collaboration between the MFA of Finland, MTT Agrifood Research Finland, IFPRI, ILRI, ICRAF, Bioversity International, University of Helsinki and HAMK University of Applied Sciences # Photo BovineSNP50 v2 BeadChip (Illumina Inc., San Diego, CA) www.illumina.com & DNA drawing http://www.farma.ku.dk Karen Marshall, Stanly Tebug, Jarmo Juga, Miika Tapio and Ayao Missohou The breed or cross-breed type of the dairy animals may not be accurately known by their owner DNA samples are taken by removing hair follicles The animal’s breed type is determined by examining the DNA for breed specific sequence changes called single nucleotide polymorphisms (SNP)# Analysis output for Senegal Dairy Genetics animals with each point representing an animal and each colour a different breed-type
