100 Fascinating Facts About Cows
Cows are amazing animals that play an important role in human society. Here are 100 fascinating facts about these gentle bovines.
1. There are around 1.5 billion cows in the world. This makes cows one of the most populous large mammals on the planet.
2. Cows belong to the subfamily ‘Bovinae’ under the family ‘Bovidae’. This subfamily includes other cloven-hoofed, ruminant mammals like buffaloes, bison, yaks, and antelopes.
3. Cows are herbivores, meaning they only eat plants. Their diet mainly consists of grasses, herbs and shrubs.
4. Cow stomachs have four compartments – the rumen, reticulum, omasum and abomasum. This specialized digestive system allows them to break down tough plant material.
5. Cows regurgitate their food from the rumen back to their mouth to chew it again in a process called “rumination” or “chewing the cud”. This allows more thorough breakdown of plant material.
6. The average dairy cow weighs around 1,200 pounds. However, breeds like the Chianina bull can weigh up to 2,600 pounds.
7. A cows normal body temperature ranges between 101.5°F and 102.5°F. This is slightly higher than the average human body temperature.
8. Cows have almost total 360-degree panoramic vision. They can see all around themselves without needing to move their heads thanks to the placement of their eyes.
9. Cows have a great sense of smell and can detect odors up to 6 miles away. This helps them identify food sources or predators.
10. An average cow eats around 40-50 pounds of feed per day. This consists mostly of hay, silage, grains and protein supplements.
11. When grazing, cows spend around 8 hours per day eating. Cows are unusual in that they will overeat even when they do not need the nutrition.
12. A cows teeth slowly erode throughout its life as a result of grazing. Most cows end up losing almost all of their teeth by the age of 15.
13. Cows drink anywhere between 20-50 gallons of water each day. That’s how they produce all that nutritious milk!
14. Dairy cows can walk up to 3 miles daily between the barn, pasture and milking parlor. The daily exercise contributes to their health.
15. The gestation period of a cow is 9 months. This is similar to humans but longer than many other domesticated animals.

17. Some cows like riding or being brushed as much some like food! Cows really enjoy being groomed and will readily present their head and neck to be brushed.
18. Cows actually do not bite grass; instead they curl their tongue around it. Cows have no upper front teeth but rather a thick dental pad for efficiently curling grasses.
19. Cattle have an excellent memory – they can easily remember faces as well as negative and positive experiences for over 2 years. So be nice to your cows!

21. Cows spend about 8 hours per day lying down chewing their cud to support rumination.
22. Cows lick each other as a means of social bonding or reducing irritations.
23. Cows ruminate longer when they are full to increase digestion efficiency. Happy cows are lying down ruminating after a good meal.
24. The average walking speed of a cow is around 2 to 4 mph.
25. Though cows sleep less than humans do, they can have dreamed. REM sleep comprises around 5% of a cows sleep.
26. Cows use different vocal sounds to communicate specific needs such as hunger, fear, anger or anxiety. Attentive farmers can interpret cow mood based on vocalizations.
27. Cow udders can hold between 25-50 pounds of milk daily. Top producing cows give over 125 pounds of milk a day – that’s a lot of milk supply!

84. The dairy orphan calf industry raises calves for gradual herd expansions at centralized sites instead of on individual farms. This allows improved nutritional protocols and environmental management for healthier calf development.
85. Most commercial ice cream makers use ‘overrun’ injecting air into ice cream to increase frozen dessert volume thereby reducing costs of goods. Premium ice creams tend to have lower overrun rates.
86. Milk protein concentrate (MPC) has exceptionally high protein content with reduced lactose and minerals, amenable for boosting protein in shakes, bars and high protein formulations.
87. Cow milk the most prominent source of commercial casein protein from casein curds. Rennet coagulated milk forces casein precipitation leaving behind the liquid whey.
