Myotonic (Fainting)

The Myotonic goat, also known as the Fainting goat, is a domestic meat and pet breed developed in the United States. Its name comes from myotonia congenita, an inherited condition that makes the skeletal muscles contract and hold for a few seconds whenever the animal gets surprised or excited. The goat does not pass out. It simply stiffens, and younger or more affected animals may topple onto their side until the muscles relax.

This is a calm, friendly, good natured breed. Myotonic goats are quieter and less inclined to climb or jump compared to most other goat breeds, partly because the muscle condition limits sudden athletic movement. That trait makes them easier to fence in and manage, a plus for anyone raising goats backyard style or on a small farm lot.

Adults reach a medium size, with most animals standing between 43 and 64 cm at the withers. They come in many coat colors and can carry horns. Lifespan usually runs 10 to 15 years given routine care.

Who it suits

This breed suits raisers who want a docile, low escape goat for a small farm, a backyard lot, or a homestead. Its calm nature and reduced climbing habit make it manageable even for first time goat keepers. It also works well as a companion animal or as foundation stock for meat production, and its steady temperament holds up well under our hot, humid weather and the stress of typhoon season.

The breed's documented history starts in the 1880s in Marshall County, Tennessee. Accounts describe a farmhand named John Tinsley who arrived with a small group of goats that stiffened whenever they got startled. He moved on after a short stay, and the goats he left behind became the base population for the breed.

From that founding stock the goats spread through the region, with a notable population building up around Marshall County and later in Texas, where breeders selected bigger animals for meat. Since the goats were easy to contain, farmers sometimes kept them alongside flocks of sheep, as a startled goat would stiffen rather than scatter whenever a predator came near.

For most of the 20th century the breed stayed a regional, working animal known mainly to local farmers. Interest picked up later on as keepers came to value the docile temperament and the unusual trait. Breed associations were formed in the United States to record pedigrees and protect the population.

The Myotonic goat is recognized today as a heritage American breed. Livestock heritage organizations have listed it as a conservation priority since its numbers stayed limited compared to mainstream commercial breeds.

The Myotonic goat has a compact, well muscled body set on relatively short to medium legs. The head is medium in length with a broad muzzle and large, prominent eyes that often look somewhat startled even at rest. Both bucks and does can carry horns. Ears are medium sized and held out to the side.

Coat and colors

Coat length varies between lines. Some animals stay short haired all year, while others grow a longer outer coat with a cashmere like undercoat during cold weather. Color is highly variable. Black and white is common, but solid and mixed patterns in brown, tan, cream, and roan also turn up. No single color defines the breed.

The Myotonic goat ranks among the calmer goat breeds. It is friendly and good natured toward people, and it usually tames easily with regular handling. The muscle condition tends to make these goats less reactive and less athletic than other breeds, so they jump and climb a lot less. That is one reason raisers describe them as easy to contain, even with simple fencing.

With family members and familiar handlers the breed is gentle and sociable. Around strangers most animals stay cautious at first but settle down quickly. Since sudden surprise can trigger stiffening, calm and predictable handling keeps unnecessary stress to a minimum. The goats are herd animals and do best with at least one companion goat rather than kept alone.

With other pets and livestock they are generally peaceful. Their quiet nature has historically let them be kept alongside sheep and other stock.

Grooming

• Brush longer coated animals during seasonal shedding to remove loose hair
• Trim hooves every 6 to 8 weeks, or as growth requires, since damp ground here wears hooves unevenly
• Check the coat for external parasites during routine handling
• Keep horns and any wounds monitored for injury

Exercise

• Give daily access to a pasture or exercise yard for grazing and movement
• Allow gentle activity; the breed climbs and jumps less than other goats
• Keep the ground level and free of hazards, since a startled goat may stiffen and fall, and keep footing dry to avoid slips during the rainy season

Environment

Myotonic goats need a dry, draft free shelter that gives shade and protects them from rain, wind, and sun, which matters even more under a hot, humid climate with a distinct rainy and typhoon season. Fencing can be lower and simpler than for athletic breeds because these goats rarely climb fences, though it still has to hold up against predators and strong winds. Provide constant access to clean water and a mineral supplement formulated for goats. Keep companions on hand, as goats are social animals and get stressed when left alone.

The Myotonic goat is a browser and grazer. The core of the diet should be good quality forage: pasture, browse such as ipil-ipil or madre de cacao leaves, and grass or legume hay whenever grazing is limited. Goats use a four chambered stomach to digest fiber, so steady forage intake keeps the rumen healthy. Grain or concentrate goes in only when forage alone cannot meet needs, such as during late pregnancy, lactation, or growth.

Treats and supplements

Provide a loose goat mineral with the right copper and selenium levels for your area, since goats have particular trace mineral needs and local soils vary. Offer salt and clean water at all times. Treats such as small amounts of fruit, vegetable peelings, or banana leaves can be given once in a while, but keep them a minor part of the diet so forage intake is not crowded out.

The Myotonic goat is considered a hardy, healthy breed with a typical lifespan of 10 to 15 years. The defining myotonia congenita is not painful or dangerous on its own; affected muscles simply contract briefly then relax. The trait can actually cut down on some injuries since the goats climb and jump less. Routine herd health practices cover most other concerns, though hot and humid conditions call for closer attention to parasite loads.

Preventive care

• Set up a vaccination and deworming schedule with a veterinarian
• Trim hooves on a regular cycle and keep bedding dry, which takes extra effort during the wet season
• Provide the right loose minerals to prevent deficiency and urinary problems
• Watch body condition and isolate new or sick animals
• Schedule routine fecal egg counts instead of blanket deworming

Myotonic goats reach sexual maturity within their first year, though many breeders wait until does are well grown, often around 8 to 12 months or older, before the first mating. Does are seasonally polyestrous and cycle roughly every 21 days during the breeding season. Gestation averages about 150 days, close to five months.

Litter size commonly runs one to three kids, with twins frequent in mature does. Kids are typically strong at birth and stand and nurse soon after. The myotonia trait is inherited, and kids may show stiffening from an early age, with the response often becoming more noticeable as they grow.

Does are usually attentive mothers. Kids nurse on the dam's milk and start sampling forage within the first weeks, then get weaned at around 8 to 12 weeks depending on the management plan. Provide a clean, dry kidding area and check newborns for warmth and successful nursing, since chilling can still happen on cold, rainy nights even in a warm climate.
