A Reference Genome Assembly of Simmental Cattle, Bos taurus taurus. [PDF]
J Hered, 2021 Genomics research has relied principally on the establishment and curation of a reference genome for the species. However, it is increasingly recognized that a single reference genome cannot fully describe the extent of genetic variation within many ...

Domestic cattle (Bos taurus taurus) are motivated to obtain forage and demonstrate contrafreeloading. [PDF]
PLoS One, 2018 Domestic cattle (Bos taurus taurus) are adapted to digest high-roughage diets, but in confinement they are commonly fed low-roughage, high-energy diets. This practice may leave cattle with an unfulfilled need to consume forage.

Diversity and evolution of 11 innate immune genes in Bos taurus taurus and Bos taurus indicus cattle [PDF]
Proceedings of the National Academy of Sciences, 2009 The Toll-like receptor ( TLR ) and peptidoglycan recognition protein 1 ( PGLYRP1 ) genes play key roles in the innate immune systems of mammals. While the TLRs recognize a variety of invading pathogens and induce innate immune responses, PGLYRP1

Biology of Reproduction, 2012 Lipid droplets, subspecies (Bos taurus indicus vs. Bos taurus taurus), and in vitro culture are known to influence cryopreservation of bovine embryos. Limited information is available regarding differences in membrane lipids in embryo, such as phosphatidylcholines (PC) and sphingomyelins (SM).

Theriogenology, 2011 The number of oocytes recovered from Bos taurus indicus females subjected to ovum pick-up averaged two to four times greater compared to Bos taurus taurus females. The objective of the present study was to test the hypothesis that this difference in oocyte yield was due to more preantral follicles in the ovaries of Bos indicus females. Ovaries (n = 64)
