Cows can naturally live as long as 15-20 years, sometimes even more. Dairy cows are usually slaughtered at approximately six years of age, or when they can no longer produce milk.
What is the life expectancy of a cow?
The productive lifespan of average cows is between 2.5 and 4 years in most developed dairy industries. Cows calve for the first time at 2 years of age, which brings their total lifespan from birth to death between 4.5 to 6 years. The natural life expectancy of dairy cattle is approximately 20 years, however.
We can argue that it might be more economical to keep a barren cow a year than to purchase a replacement heifer but I choose to keep pressure on the cow herd to be productive. Reproduction isn’t a highly heritable trait but selecting cows and heifers that are productive in our particular environment is a good long-term goal.
“Beef” cattle: 18 months: 15-20 years: Chickens (egg laying hens) 18 months: Up to 8 years: Pigs (breeding sows) 3-5 years: 10-12 years : Dairy cows: 4 years: 15-20 years.
How do cows survive?
As clearly articulated, cows can survive in the wild by creating social groups whereby they keep together and protect themselves from predators. Most animals have the ability to see in the dark and have a superior sense of smell which allows them to survive in varied environments. The same applies to most domestic animals.
The next thing we wanted the answer to was how do cows survive in the hot weather?
The Animal Humane Society of Minnesota offers the following suggestions for protecting your indoor and outdoor pets during harsh winter conditions: During severe weather, dogs should go outside only to relieve themselves and cats should be kept indoors at all times.

Remove any ice, salt and caked mud from your pet’s paws and fur immediately., and more items.
