Cattle (colloquially cows) are the most common type of large domesticated ungulates. They are a prominent modern member of subfamily Bovinae, are the most widespread species of the genus Bos, and are most commonly classified collectively as Bos primigenius. Cattle are raised as livestock for meat (beef and veal), as dairy animals for milk and other dairy products, and as draft animals (oxen or bullocks). Other products include leather and dung for manure of fuel. In 2009, cattle became the first livestock animal to have a fully mapped genome.
The genome of a female Hereford cow has been sequenced by the Bovine Genome Sequencing and Analysis Consortium, a team of researchers led by the National Institutes of Health and the U.S. Department of Agriculture. It is ont of the largest genomes ever sequenced.
The size of the bovine genome is 3 Gb (3 billion base pairs). It contains approximately 22,000 genes of which 14,000 are common to all mammalian species. Bovine share 80 percent of their genes with humans, but cows are much more similar to humans than rodents.
NABIC Omics database has two assemblies, one is UMD 3.1 and the other is alternative assembly 4.6.1. Each information can be searched in GBrowse.
