Research Project: Database Creation for Industry Cattle Population Utilizing Phenotypic and Genomic Information Project Number: 5438-31000-092-04
Project Type: Specific Cooperative Agreement

Start Date: Jun 01, 2013
End Date: Mar 31, 2014

Objective:
Create and maintain a phenotypic and genomic database for cattle in industry populations that will be used for the validation of DNA associations found in the research population at USMARC. Characterize said populations and analyze data as appropriate for validation.

Approach:
Collaborators with USMARC scientists are developing external validation populations comprised of industry animals. Data from these populations are collected by collaborators and by breed associations. These data will be transferred to UNL for quality assessment, summary analysis, storage and retrieval. DNA samples for these animals will be analyzed for appropriate genotypes. Associations between SNP genotypes discovered in the USMARC discovery population will be made to create Molecular Breeding Value (MBV) estimates for individual animals. Data will be analyzed for the association of the MBV’s with Expected Progeny Differences (EPD) or phenotypic information.
