Bos taurus (cow) is an agriculturally important animal; beef and milk production are the largest manufacturing industries in the United States. The cow is an important model organism for health research in obesity, female health, and infectious diseases. Cow is also used in studies of endocrinology, physiology and reproductive techniques. The cow genome will be useful for comparative genomics, representing a non-primate, non-rodent eutherian genome. The B. taurus genome is estimated to be 3000 MB, organized in 29 pairs of autosomes and two sex chromosomes. Bovine chromosomes are acrocentric.
