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

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)#
