Livestock uses precise terminology to classify animals based on their sex, age, and reproductive status. For those interested in goat (caprine) husbandry, understanding these terms is important for management and communication. The specific name for a male goat that has been castrated, meaning his testicles have been removed or rendered non-functional, is a wether. This term is used universally across the industry to identify male goats that will not be used for breeding, a practice that serves several practical purposes in herd management and product quality.
The Specific Name and Common Variations
The most widely accepted term for a castrated male goat is wether, a classification shared with castrated male sheep. A wether is a male that was castrated, often as a young kid, and is therefore incapable of reproducing. This designation is applied regardless of the animal’s age after the procedure has been completed.
While “wether” is the standard industry and show-ring terminology, some regional or historical terms may be encountered. When referring to a castrated male goat intended for meat, the term “mutton” might be used, although this term is more commonly associated with sheep meat. The term “wethered goat” is occasionally heard, but it describes the animal’s status rather than serving as the primary noun.
The word “wether” is dominant because it clearly distinguishes the animal from an intact male. Since the intact male goat is known as a buck (or billy), using a separate term prevents confusion about the animal’s temperament, reproductive capacity, and suitability for meat production. This precise nomenclature allows producers to communicate effectively about the role of the animal within a herd, whether for fiber, meat, or as a companion animal.
Why Male Goats Are Castrated
Castration is performed on male goats primarily for management, meat quality, and herd control. Intact males, known as bucks, develop behaviors that make them difficult to handle, particularly during the breeding season known as the rut. Bucks become significantly more aggressive toward other animals and humans, often exhibiting head-butting.
Bucks develop a strong, unpleasant odor during the rut due to scent glands and the behavior of urinating on their own faces and beards. This strong smell, sometimes called “buck taint,” can permeate the meat of intact males, making it undesirable for consumption. Castrating the male removes the source of the hormones responsible for this scent and behavior, resulting in a cleaner, better-tasting meat product.
Preventing unwanted or premature breeding is another significant reason for creating wethers. Male goat kids, known as bucklings, can become sexually mature and fertile at a surprisingly young age. Castration ensures that only genetically superior males, selected as herd sires, are able to reproduce, thereby improving the overall quality of the herd. Producers can house the non-breeding males with females without the risk of accidental pregnancy.
Defining Other Goats in the Herd
To understand the role of the wether, it is helpful to know the terminology for the other classifications of goats in a herd. The intact, sexually mature male goat is called a buck, though the casual term billy is also widely used. Bucks are kept specifically for breeding.
The female goat is formally known as a doe, with the common alternative being nanny. A doe is a sexually mature female, and a female that has not yet reached maturity is often called a doeling. The process of a female goat giving birth is called “kidding.”
All young goats, regardless of sex, are referred to as a kid from birth until they are roughly six months to one year old. A young, intact male is specifically a buckling, while a young female is a doeling. Distinguishing between these terms is fundamental for the care and management of goats.
