What Are Male Cows Called? Bulls, Steers, and Oxen

The term “male cow” refers to male bovine animals, which are classified based on age, reproductive status, and purpose. This article clarifies these terms and provides a comprehensive understanding of male cattle, their characteristics, and their varied roles within agriculture.

Understanding Male Cattle Terminology

The primary term for an intact adult male bovine is a “bull.” Bulls are uncastrated and capable of breeding. A “steer” refers to a male bovine that has been castrated, typically at a young age, before reaching sexual maturity. Castration prevents the development of masculine characteristics and reduces aggressive behavior. An “ox” is generally a castrated male cattle, usually over four years of age, that has been trained specifically for draft work, such as pulling plows or carts. Finally, a “calf” is a young bovine of either sex, usually under one year old. A male calf is specifically known as a “bull calf.”

Distinct Physical and Behavioral Traits

Bulls, as intact adult males, exhibit distinct physical traits. They are typically larger and more muscular, often weighing significantly more than cows of the same breed. Bulls often possess a prominent hump on their shoulders and have thicker, shorter horns. Their musculature is particularly pronounced in the shoulders, neck, and hindquarters.

The presence of testosterone in bulls contributes to their more aggressive and dominant behavior, often leading to territoriality. In contrast, steers are generally more docile and calmer due to the absence of testosterone, making them easier to handle. While steers can grow to a large size, they lack the pronounced musculature and aggressive temperament of bulls. Their behavior is closer to that of females, as castration impacts their hormonal profile and disposition.

Primary Roles in Agriculture

Male cattle serve various important functions in agricultural practices. Bulls are primarily used for breeding, playing a crucial role in herd maintenance by impregnating cows and heifers. Many farms utilize artificial insemination, but bulls are still kept for natural breeding. In beef production, steers are the main focus. They are raised specifically for meat, as castration leads to more tender beef with better marbling and a less gamey flavor. Steers are easier to manage in feedlots due to their reduced aggression.

Historically, oxen are used as draft animals. Their strength and endurance make them capable of pulling heavy loads, plowing fields, and powering farm machinery. Oxen are advantageous for tasks requiring steady, sustained pulling, and they can thrive on rougher forage than horses. While less common in mechanized agriculture, oxen remain significant in regions where heavy machinery is impractical. Male cattle are generally not used for dairy production, as milk production is exclusive to female cattle.
