We answer the question of how long cows live, and the impact of farming on the lives of cows.

Many people believe that, compared to the beef industry, dairy production is more humane. People mistakenly believe animals don’t die to produce dairy, and that milk production is natural. Sadly, this isn’t true. Just like in the beef industry, dairy cows too are slaughtered well short of their natural lifespan, all in the name of profit.
In fact, regardless of the industry, on factory farms all cattle have their lives cut short by at least a decade. Within the dairy industry, some male calves are even slaughtered within mere hours of being born. Ultimately, there is no such thing as retirement for animals in agriculture.
Let’s take a look at how long cows would live naturally, versus the short and miserable lives they live on factory farms.
Do cows die of old age?
It’s very rare today for any cow to die of old age. Instead, most cows are killed at just a few years old for meat, or when they are no longer able to produce enough milk to be profitable.
What is the natural life expectancy of a cow?
Cows naturally live for about 20 years. There are some cows, however, who have made it well past that. Joy, a holstein cow in California, reached an impressive 30 years of age.
What are some factors affecting the lifespan of a cow?
As with people, there are many factors that determine how long a cow lives, including:
- Health
- Nutrition
- Breed
- Management
- Genetics
Of all of these factors, management typically plays the biggest role in how long a cow lives, as it dictates how old a cow is when producers decide to send them to slaughter.
How long do dairy cows live?
Dairy cows are killed at around 4-6 years of age, when they’re no longer able to produce the large amount of milk necessary to be considered profitable.
Over the last few decades, producers have been demanding higher yields from cows. In just the last two decades, milk production per cow has shot up. In 2003, the average British dairy cow produced 6,763 litres of milk annually. In 2023 that number jumped to 8,219 litres.
Producing all that milk takes a toll on cows’ bodies, as they are simply not able to maintain such high yields for longer than a few years.
How long do cows raised for beef live?
Most beef cattle are killed at just under two years old - one tenth their natural lifespan.
How long do bulls live?
Only a small percentage of specially bred bulls are kept for breeding. Most are killed much younger, depending on whether they’re a dairy or beef breed.
The bull stud industry is booming. Estimates suggest that the British bull semen market is worth £50 million. While most male calves end up slaughtered after just a few years, stud bulls are the exception, kept for about a decade, or roughly half of their natural lifespan.
Instead of naturally impregnating cows, bulls are usually kept on stud farms, where they are repeatedly ‘stimulated’ by handlers. Their ejaculate is then separated into small tubes, frozen, and sold to farms where female cows are artificially inseminated by workers. While the use of artificial insemination and stud cattle is much more common within the dairy industry, it’s now also growing in popularity in the beef industry.
How long do calves live?
Calves have different lifespans, depending on their sex and breed. The sex of calves born in the beef industry doesn’t really matter, as both are raised and slaughtered for meat. For dairy cattle, though, sex is an important factor.
Female dairy calves are likely to be raised to become dairy cows themselves, enduring repeated pregnancies until their bodies give out. Male dairy calves are likely to be killed soon after birth, or sold for veal. In the UK, calves kept for veal enjoy minimal protections; across most of the rest of the world, veal calves are granted far fewer protections.
Some male dairy calves may be sold to be raised for lower-grade ground beef, as their flesh isn’t considered to be as high quality as beef cattle. These calves will be killed at just over a year old.
How are cows slaughtered?
Whether raised for meat or dairy, most cattle end up at a slaughterhouse. Here they will first be stunned using a captive bolt gun, then be strung up by their feet, stabbed, and drained of blood, before being butchered into the various cuts of meat you see in the grocery store.
Slaughterhouses are terrifying places where, according to people who have worked there, the walls are covered in blood and the floors are full of filth. Another disturbing facet of slaughterhouses is the putrid smell - the result of animal death and fear.
Making matters worse, the trip to the slaughterhouse is also very stressful for the animals. By the time they arrive, cows are likely to have endured long hours without access to food, water or rest, and may have been subjected to extremely hot, cold or wet weather.
Why do some cows live longer lives?
The simplest answer is that they’re just not slaughtered. If a cow is surrendered to a sanctuary, or was not raised on a factory farm at all, they can live decades. High-quality care can also help maximise just how long a cow lives. This can include:
Ample space and proper shelter
Providing plenty of space - complete with safe, secure shelter that protects cows from the elements - is an important part of high-quality care. Despite being herd animals who enjoy the company of others, many dairy farms still overcrowd their cattle, failing to provide the space they need to lay down and relax.
Lots of clean water
Staying hydrated is one of the most important facets of staying healthy, both for people and cattle. A growing 400-pound calf requires around 5.8 gallons of water every day, whereas a 1200 pound adult cow would require about 12 gallons of water a day.
The chance to graze
Grazing on grass is a natural behaviour for cattle. Sadly, on many dairy farms, cows are instead fed as they’re being milked and spend most of their lives in barns, unable to graze fresh grass.
Regular grooming
Regular grooming ensures that a cow’s coat and skin are healthy. Grooming is also a great way to check for injuries and overall physical health.
A rich social life
Cows are social animals who thrive off of living in groups. They will make friends with other cattle, and so living in a herd is an important part of ensuring cows are mentally healthy and fulfilled.
Health care and disease prevention
Just like our companion animals, cattle should routinely see a veterinarian. A veterinarian may notice conditions in their early stages before they develop into something more severe and painful.
The bottom line
Sadly, most cows on earth are valued only for their ability to generate income for humans. Thus the length of their lives - whether that’s hours, months, or years - is usually based on how much money they can generate, and for how long.
But cows have much more value beyond their use for humans. They are social creatures with rich lives - when given the chance to live naturally. Join us in our fight to end the abuse of animals raised for food.
