Cattle, with their majestic presence and iconic appearance, have long been a part of human civilization. One question that often arises is whether female cows have horns.
In this comprehensive guide, we will explore the intriguing world of bovine anatomy and shed light on the presence or absence of horns in female cattle.
Let’s unravel the mystery and discover the factors that determine whether female cows have horns or not.
Understanding Horns in Cattle
Horns are bony structures that grow from the skull and are found in various animal species, including cattle.
They serve different purposes, such as defense, social hierarchy, and heat regulation. It is important to note that not all cattle have horns, and the presence or absence of horns can vary based on several factors.

Horned vs. Polled Cattle
Cattle can be broadly classified into two categories based on their horn status:
1. Horned Cattle
Horned cattle refer to individuals of both sexes that naturally develop horns. These include breeds like Longhorn, Scottish Highland, and Ankole-Watusi.
Both male and female horned cattle possess horns, although there may be differences in size and shape.
2. Polled Cattle
Polled cattle are individuals that naturally lack horns due to a genetic mutation. Polled animals can be either male or female.
Through selective breeding, specific breeds have been developed, such as the Polled Hereford and the Angus, where polled characteristics are prevalent.
Factors Influencing Horn Development in Female Cows
The presence or absence of horns in female cows can be influenced by multiple factors:
1. Genetics
Horn development in cattle is primarily determined by genetic factors. Certain breeds are naturally horned, while others have been selectively bred for polled characteristics.
Breeding two horned cattle will usually result in horned offspring, whereas breeding two polled cattle will produce polled offspring.
However, the genetics of horned and polled traits can be complex and depend on various genetic markers.
2. Selective Breeding
Selective breeding has played a significant role in shaping the horn status of cattle. By intentionally breeding cattle with or without horns, breeders can manipulate horn traits over generations. This process has resulted in the establishment of specific horned and polled breeds.
3. Hormonal Influence
Hormonal factors can also play a role in horn development. Testosterone, a male hormone, is associated with horn growth and development. While female cows have lower levels of testosterone, some females may exhibit small, rudimentary horns or “scurs.”
4. Age and Individual Variation
Horn development can vary among individual cows and may be influenced by age. In some breeds, females may start developing horns as they mature, although these are often smaller and less prominent compared to males.
Dehorning Practices
In some instances, cattle may undergo a process called dehorning, which involves the removal of horns.
Dehorning is typically performed for safety reasons and to prevent injuries to other animals or humans.
It is important to note that dehorning should be carried out by trained professionals using proper techniques and pain management protocols to ensure the welfare of the animals.

Conclusion
In conclusion, whether female cows have horns or not depends on various factors, including genetics, selective breeding, hormonal influences, age, and individual variation.
Some breeds exhibit horned characteristics in both males and females, while others have been selectively bred for polled traits.
Understanding the factors that influence horn development in female cows provides valuable insights into the fascinating world of bovine anatomy.
Whether horned or polled, female cows continue to be an integral part of our agricultural and cultural heritage.
Here are some FAQs about whether female cows have horns:
1. Do female cows have horns?
Yes, female cows (like their male counterparts, bulls) can have horns. Both male and female cattle of certain breeds are born with the potential to grow horns, as horn growth is determined by genetics, not by gender.
2. Do all breeds of female cows have horns?
No, not all breeds of female cows have horns. Some cattle breeds, known as polled breeds, are genetically hornless. Examples of polled breeds include:
- Aberdeen Angus
- Red Poll
- Polled Hereford Cows from horned breeds, such as Holsteins, Herefords, or Texas Longhorns, will have horns unless they are selectively bred to be polled or are dehorned.
3. Why don’t some female cows have horns?
Female cows may not have horns because:
- They are from a polled breed, which is genetically hornless.
- They have been dehorned (a common practice in farming where horns are removed when the cow is young).
- They have been bred specifically to be polled through selective breeding practices.
4. At what age do female cows start growing horns?
Female cows (and bulls) typically start developing horn buds within a few months of birth, and their horns continue to grow throughout their lives unless they are dehorned. The growth rate can vary depending on the breed.
5. Why are some cows dehorned?
Dehorning is a common practice in the cattle industry for several reasons:
- Safety: Dehorning reduces the risk of injury to other cattle, humans, and farm equipment.
- Management: Cows with horns can be more difficult to handle in crowded environments like barns and feedlots.
- Preventing injuries: Horns can cause injury to other animals or handlers, especially in close quarters.
6. Are female cows born with horns?
Female cows are not born with fully developed horns, but they do have horn buds shortly after birth. The horns begin to grow gradually as the cow matures. Some farmers may choose to disbud young calves to prevent horn growth.
7. Do dairy cows have horns?
Many dairy cow breeds, like Holsteins and Jerseys, can grow horns. However, most dairy farms practice dehorning or raise polled (hornless) cows for easier management and safety.
8. How are cows dehorned?
Cows are typically dehorned using one of the following methods:
- Disbudding: This is done on young calves and involves removing the horn buds before they grow into full horns, often with a hot iron or caustic paste.
- Dehorning: This is done on older cattle and involves physically removing the horns using tools such as saws or cutters.
- Selective breeding: Breeding for polled traits (genetically hornless cattle) is becoming a more common way to avoid the need for dehorning.
9. Why do some cows still have horns on farms?
Some farmers choose not to dehorn their cows, especially in heritage breeds or show cattle where horns are part of the breed’s standard. Additionally, some farms may have enough space for the cows to roam freely without risking injury from horns.
10. Do female cows in the wild have horns?
In wild or feral cattle populations, both males and females generally have horns, as they serve a purpose in defense and social hierarchy. Horns can be used for protection against predators or as a tool in competing for resources.
11. Do female cows use their horns for protection?
Female cows, like bulls, can use their horns for protection. In the wild or on farms with horned cattle, cows may use their horns to defend themselves from predators or to establish dominance within the herd.
12. Are horns in cows related to milk production?
No, horns are not related to milk production. A cow’s ability to produce milk is determined by genetics, nutrition, and health, not by whether or not the cow has horns.
13. Do polled cows (without horns) occur naturally?
Yes, polled cows can occur naturally. Some breeds, like Angus and Polled Hereford, have been selectively bred to be genetically hornless. These cows do not develop horns at any stage of life.
14. What is the difference between horned and polled cattle?
The key difference is that horned cattle have the genetic ability to grow horns, while polled cattle are genetically hornless. Polled cattle do not have horn buds and will never develop horns.
15. Do female cows in all cultures have their horns removed?
Dehorning practices vary by region and culture. In some cultures, horned cattle are valued and kept as part of tradition or aesthetics, while in other regions, dehorning is common for practical reasons such as safety and ease of management.
16. Are horns more common in certain cow breeds?
Yes, horns are more common in certain breeds, especially heritage breeds or beef breeds, such as:
- Texas Longhorn
- Highland Cattle
- Watusi Cattle
- Hereford (in non-polled varieties) In contrast, many dairy breeds and modern beef cattle have been bred to be polled (hornless).
17. Do female bulls have horns?
The term “bull” refers to a male cow. Female cows are just called cows. Both male and female cattle can grow horns depending on their breed and genetics.
18. Do female cows have larger horns than males?
In breeds where both males and females have horns, bulls (males) typically have larger, thicker horns than cows (females). However, this varies depending on the breed and individual genetics.
19. Do horns affect a cow’s behavior?
Cows with horns may behave differently in terms of social hierarchy and defense within a herd. Horns can be used as a tool for dominance, and horned cows may exhibit more assertive behaviors. However, behavior is influenced by many factors, including temperament and environment.
20. Can dehorning harm cows?
Dehorning can be painful for the cow if not done properly or at the right age. However, most farmers practice disbudding (removing the horn buds when calves are very young), which is less painful and heals more quickly. Veterinarians often recommend pain relief or anesthesia during dehorning procedures to minimize discomfort.
