About the Project
The BCM-HGSC sequenced and analyzed the bovine genome (Bos taurus). The initial bovine genome assembly and analysis and the study of cattle genetic history were published April 24, 2009. Ongoing efforts to improve the genome are centered around finishing the Y chromosome.
The source of the BAC library DNA was Hereford bull L1 Domino 99375, registration number 41170496. Dr. Michael MacNeil's laboratory, USDA-ARS, Miles City, MT, provided the blood. The DNA for the whole genome shotgun sequences was provided by Dr. Timothy Smith's laboratory, U.S. Meat Animal Research Center, Clay Center, NE, from white blood cells from L1 Dominette 01449, American Hereford Association registration number 42190680 (a daughter of L1 Domino 99375). A skin cell fibroblast cell line from the same animal is available from Dr. Carol Chitko-McKown's laboratory, although there is no sequence from that cell line.
Funding for this project has been provided by: the National Human Genome Research Institute (NHGRI U54 HG003273), which is part of the National Institutes of Health (NIH); the U.S. Department of Agriculture's Agricultural Research Service and Cooperative State Research, Education, and Extension Service (USDA ARS Agreement No. 5 9-0790-3-196 and CSREES Agreement No. 2004-35216-14163); the state of Texas; Genome Canada through Genome British Columbia, The Commonwealth Scientific and Industrial Research Organization of Australia (CSIRO); Agritech Investments Ltd., Dairy Insight, Inc. and AgResearch Ltd., all of New Zealand; the Robert J. Kleberg, Jr. and Helen C. Kleberg Foundation; and the National, Texas and South Dakota Beef Check-off Funds.

Access to the Data
The final draft assembly (7.1 coverage) and the two previous assemblies are available for download as contigs or linearized scaffolds by using the BCM-HGSC data links in the sidebar. The assemblies are described in more detail in the README files.
HGSC provides BLAST searches of the genome assemblies, either as contigs or as linearized chromosome sequences. The WGS sequence enriched BAC assemblies and the unassembled reads (sequencing reads that did not end up in the genome assembly) can also be searched by BLAST. The BLAST link is located in the sidebar.
Traces are available from the NCBI Trace Archive by using the link in the sidebar or by using NCBI MegaBLAST with a same species or cross species query.
