Genome-wide Association Study For Milk Traits In Buffaloes - Rommel Herrera

Genome-wide Association Study For Milk Traits In Buffaloes - Rommel Herrera

PhD Student, University of New England

Tuesday 3rd April 2018.

Selection of dairy buffalo (Bubalus bubalis) bulls in the Philippines so far is based on the milk performance of their daughters (progeny testing). However, this takes seven years before the identification of the “best” bulls. With the availability of a medium density DNA chip for buffalo, it is now possible to genotype 90,000 markers (single nucleotide polymorphism: SNPs) per animal. Based on these SNP markers, it is now possible to predict the breeding value of a bull even without production data, thus reducing the generation interval and hastening genetic progress. It is also possible to identify chromosome regions very close to these markers that contain genes with large effects related to desired traits. To do this, a genome-wide association study (GWAS) is conducted, wherein animals with performance data (milk traits: milk yield, fat yield and protein yield) are genotyped and significant SNP markers associated with the above traits are identified. To know more about this topic, you are all invited to attend the ASS this coming April 3 and here Rommel will talk about “Genome-wide association study for milk traits in buffaloes”.
