Research Project: Improving Fertility of Dairy Cattle Using Translational Genomics

Location: Animal Genomics and Improvement Laboratory

Project Number: 8042-31000-101-05
Project Type: Reimbursable

Start Date: Jan 01, 2013
End Date: Dec 31, 2014

Objective:
To perform genetic evaluations, genomewide association studies, and bioinformatic analyses to identify genomic regions associated with daughter pregnancy rate, fertilization ability, and early embryonic development in dairy cattle. To entify putative causal relationships among traits. To determine optimal strategies for including genomic information in analyses.

Approach:
ARS will provide expertise in genetic evaluations, genomewide association studies, and bioinformatic analyses to identify genomic regions associated with daughter pregnancy rate and early embryonic development in dairy cattle. This information will be used by both parties to jointly identify putative causal relationships among traits and determine optimal strategies for including genomic information in analyses. The Cooperator will provide phenotypic measurements of early embryonic development, genotypes for about 500 dairy bulls using a candidate gene SNP chip, and expertise in bioinformatics and functional biology. The Cooperator will apply for funding through the USDA-AFRI grant program.
