Interesting facts about cows.
Is cow tipping real? Do cows make friends? How many udder squirts does it take to fill a gallon of milk?
Here are a few interesting facts about cows:
- Cows spend 10 to 12 hours a day lying down.
- The average sleep time of a domestic cow is about four hours a day; unlike horses, they don’t sleep standing up.
- Drunken rural carousers swear by their stories of tipping over cows in the middle of the night, but most experts assert that there’s more urban myth going on than actual tipping. A 2005 study at the University of British Columbia concluded that tipping a cow would require an exertion of 2,910 newtons of force; meaning that a 4’7″ cow pushed at an angle of 23.4 degrees relative to the ground would require the equivalent strength of 4.43 people to tip the poor thing over.
- According to Stanford University, livestock account for anywhere between 18 and 51 percent of global greenhouse gas emissions measured in CO2 equivalent.
- There are about 350 udder squirts in a gallon of milk.
- Researchers have found that if you name a cow and treat her as an individual, she will produce almost 500 more pints of milk a year.
- A German study found that cows tend to face either magnetic north or south when grazing or resting, regardless of the sun’s position or the wind’s direction. The study’s author says that magnetic compass orientation has been relatively under-studied in mammals; why cows use it remains a mystery.
- Cows have favorite friends and become stressed when they are separated. In a study measuring isolation, heart rates and cortisol levels, researcher Krista McLennan concluded that, “When heifers have their preferred partner with them, their stress levels in terms of their heart rates are reduced compared with if they were with a random individual.”
- Cows can have regional accents. After a group of dairy farmers noticed their cows had different moos, language specialists determined that, “In small populations such as herds you would encounter identifiable dialectical variations which are most affected by the immediate peer group.”
- Cows have an excellent sense of smell and can detect odors up to six miles away.
