How Long Does A Bull Live? Bulls typically live between 10 and 12 years, although in most agricultural environments they are removed from service or killed after 4 to 5 years due to injuries, temperament, or low fertility. Although their natural lifespan can exceed 15-20 years, the practical lifespan of breeding stock is usually limited to around 7-8 years.
The lifespan of a bull depends greatly on its “career” and management. Although they have the natural biological capacity to live for decades, most are slaughtered or killed much earlier for economic reasons.

Key Factors in a Bull’s Lifespan:
- Natural Lifespan: If left in a shelter or as a pet, bulls typically live 18 to 22 years. Some can even reach 25 to 30 years in ideal conditions.
- Active Service Life: Most working bulls are killed after 4-5 years (often after failing a breeding test) due to foot, leg, or structural problems.
- Breeding Bulls: Most commercial bulls are kept in the herd for only 4 to 5 years. After that, they are often killed due to declining fertility, injuries, or temperament problems, although some hardy bulls can remain in service for up to 10 to 12 years.
- Beef Bulls: Male cattle raised specifically for meat (often castrated and called steers) are usually slaughtered between 18 and 24 months of age to ensure the best quality meat.
- Bucking Bulls: Professional bucking bulls (such as those in the PBR) typically have a competitive career of 2 to 4 years, although some compete for up to 10 years. After retirement, they often live like roots until they die of natural causes at the age of 15.
- Causes of Early Death: According to Beef Magazine, aggressive behavior, poor offspring performance, or failure to conceive cows often shorten their lives.
- Genetic Factors: Longevity is highly dependent on structural health and fertility.
Factors Affecting Longevity
- Health and Fitness: Large, heavy breeds (such as Charolais) are more prone to foot and joint problems, which can lead to early death.
- Temperament: As bulls mature, they can become more aggressive (“snotty“). This often leads to their removal from the herd for the safety of handlers.
- Productivity: Once a bull’s offspring no longer improve the genetics of the herd, or if it fails the breeding soundness test, it is usually sent to market.
Bulls Typical Lifespan
| Context | Typical Lifespan | Key Determining Factors |
|---|---|---|
| Natural/Non-Commercial | 15-25+ years | Genetics, healthcare, sanctuary care. |
| Beef Production | 18-20 months | Market weight efficiency; reaching “finish” weight. |
| Breeding Service | 4-5 years (avg. use) | Fertility, structural soundness, temperament, genetic contribution. |
| Dairy Industry | Variable (often young) | Used for natural service or semen collection; culled when not profitable. |
Breeding Bulls: Peak Years
Bulls breed for 4-8 years, producing viable sperm for 30 cows/season before fertility declines by 50% by age 10. Passers-by live an average of 12 years, costing $600/season of winter hay but gaining genetic advantages. AI increases efficiency – a bull produces thousands of sperm, allowing elites like Full Throttle to reach stud for 20 years alone.
History of Bull Lifespan Management
Bulls trace their origins to the Pleistocene aurochs (extinct by 1627), which stood 6 feet tall at 2,000 pounds, living for 15-20 years in Eurasian forests on a grassy diet. US ranching evolved the cattle drive after the 1800s: early cowboys killed for meat at 3 years of age; modern AI breeding (since the 1950s) allows studs to live 10-15 years, using 30+ cows annually.
19th-century rodeo pioneers selected aggressive bulls for booking, shortening careers but extending retirement – the PBR (founded 1992) formalized this with longevity protocols, increasing the average by 5 years. Echoing horse whispering practices, techniques shifted from whiplash training to positive reinforcement.
Expert Insights and On-Farm Case Studies
Experienced farmers emphasize that the working life of a good bull is a balance of care, luck, and genetics. As reported in farming forums, while some bulls last only a few years due to injury, others that are properly raised – not overfed and allowed to grow slowly – can remain strong and productive well into their early teens.
The practice of “feeding for the show ring” is frequently criticized by experienced breeders. Pushing a young bull to grow excessively for sale can lead to long-term health problems, which can shorten its useful life on a commercial farm. In contrast, bulls purchased from breeders who prioritize structural soundness and strong growth often have longer, more productive careers.

Frequently Asked Questions: How Long Does A Bull Live?
How many world titles does Ryder Wright have?
Naturally, bulls (and cattle in general) can live for 15-20 years, sometimes even longer, but in farming their lifespan is considerably reduced by industry demands for meat or milk production, often by only a few years or months, although bulls in breeding can last much longer, around 4-10 years in service.
Do rodeo bulls get killed after the rodeo?
Rodeo bulls are not usually killed immediately after a rodeo performance. Because of their high financial value, specialized training, and breeding potential, they are usually moved to ranches to make a living or used for breeding. Although some animal welfare groups say they may face slaughter when they become too old or worn out, they are not traditionally killed as part of the sport.
What is the oldest a bull has ever lived?
Although the typical lifespan of a bull in agricultural production is relatively short, typically around 10 to 15 years, some exceptional, well-cared-for bulls live much longer. A notable example of a long-lived, productive bull was the Black Angus “New Design 878,” which celebrated its 17th birthday in 2015.
What’s the oldest recorded bull?
The oldest recorded bull is commonly known as a Black Angus named New Design 878, who celebrated his 17th birthday in March 2015 while in service with ABS Global. Foaled on February 17, 1998, this prolific bull was known for his longevity and large genetic impact, producing over 700,000 units of semen.
Why are dairy bulls often killed younger?
In the dairy industry, male calves (bulls) are often killed at a very young age – often within the first week of their life – primarily because they are considered a “byproduct” for a farm focused on milk production with no economic value.
Why are dairy bulls often killed younger?
Bulls are usually culled at 4 to 5 years of age due to a combination of management, economic and physiological factors, although they can live up to 10-12 years. Cutting at this age helps maintain herd productivity, manage costs and improve genetics.
Can a bull be a pet?
Technically yes, a bull can be a pet, but experts and farmers strongly advise against it. While some individual bulls may show a gentle disposition and “dog-like” affection, they remain fundamentally unpredictable animals with immense physical strength.
How does diet affect bull lifespan?
Diet is the main driver of a bull’s health and productive lifespan, as nutritional imbalances often lead to metabolic diseases or physical impairments that result in early death.
How can you tell a bull’s age?
Age can be estimated by examining an animal’s teeth for wear or, in horned species, by counting the rings growing on the horns.
Are PBR bulls treated better for longevity?
PBR (Professional Bull Riders) booking bulls receive elite, specialized care aimed at maximizing their health, performance, and longevity, often living into their middle years. Unlike many commercial bulls who enter the feedlot by the age of three, these highly prized athletes receive advanced nutrition, veterinary care, and physical therapy for injuries.
Health Tips to Maximize Bull Life
Maximizing a bull’s health and longevity requires a strategy that encompasses nutrition, physical conditioning, and proactive veterinary care.
