Over the last fifty years, dairy farming has become more intensive to increase the yield of milk produced by each cow. The Holstein-Friesian is the breed of dairy cow most common in the UK, Europe and the United States. It has been bred selectively to produce the highest yields of milk of any cow. The average in the UK is around 22 litres per day.

SN 2018cow (ATLAS name: ATLAS18qqn; also known as Supernova 2018cow, AT 2018cow (AT = Astronomical Transient), and "The Cow") was a very powerful astronomical explosion, 10–100 times brighter than a normal supernova, spatially coincident with galaxy CGCG 137-068, approximately 200 million ly (60 million pc) distant in the Hercules constellation.
The mature cow will attempt to stop the younger one from coming near to the wallow in a vicious attack with her forelegs and if the younger female gets to lie in the wallow the older female will drive her out of it only to return to lie in it and take up as much space as possible. [33]
This could even possibly force females to seek more copulation to ensure successful reproduction. [20] These types of evidence of sperm allocation would suggest that Coolidge effect will determine how much sperm is invested into females, and if possible, sperm will be allocated so that sperm can be evenly distributed for multiple mates.
The size of the bovine genome is 2.7 Gb (2.7 billion base pairs). [4] It contains approximately 35,092 [4] genes of which 14,000 are common to all mammalian species. Bovines share 80 percent of their genes with humans; cows are less similar to humans than rodents (humans and rodents belong to the clade of Supraprimates) and dogs (humans and dogs belong to the clade of Boreoeutheria).
Artificial reproduction was not achieved because of the difficulties in hatching or feeding some farmed species such as eel and yellowtail farming. [24] A suspected reason associated with the late realization of success in selective breeding programs in aquaculture was the education of the concerned people – researchers, advisory personnel ...
