Gene
Myotonia congenita is the muscle stiffness that defines Myotonic (fainting) goats: after a sudden movement or a scare the muscles are slow to relax, and the goat may stiffen or fall over for a few seconds. It is caused by a change in the muscle chloride channel gene CLCN1 and has also been found in Nigerian Dwarfs. Sources disagree on whether one copy is enough to show it.
How Myotonia Congenita is inherited isn't settled yet.
UC Davis VGL and ADGA treat it as recessive: a goat with one copy (N/CM) is not expected to show signs. OMIA lists it as dominant, so one copy could show signs; no published goat breeding study settles it.
Goats with two copies (CM/CM) stiffen and can fall over briefly when startled, and very frequent stiffness is reported to limit how well a goat uses its surroundings. With one copy (N/CM), VGL and ADGA expect no signs; OMIA's dominant listing means signs could appear.
Results are written N/N, N/CM and CM/CM.
The Myotonic Goat Registry treats stiffness as part of breed type; the American Dairy Goat Association treats it as an undesirable disorder and records Clear, Carrier or Affected without affecting registration.
OMIA lists autosomal dominant inheritance without goat breeding data. The 2014 paper often cited for that reading is a cat study repeating a goat sentence from Beck 1996; it does not supply goat segregation data. The laboratory and ADGA describe unaffected carriers.

Guides and articles for Myotonia Congenita goat owners.
A goat itself usually costs somewhere between $150 and $800, and where a given animal lands in that range depends almost entirely on what it is for. A pet wether (a castrated male) is the cheapest, often $150 to $350, because he has no breeding or dairy value. A grade dairy doe or a commercial […]
Feed goats a diet built on forage and browse, with good hay as the year-round backbone, and add grain only when a specific animal actually needs it. Goats are ruminants, so their whole digestive system is designed to ferment long-stem fiber, not to run on concentrates. Get the forage right, keep clean water and loose […]
The goat gestation period is about 150 days (145 to 155). Use our kidding date chart, Boer, Pygmy and Nigerian Dwarf notes, and free calculator.
A doe shared a paddock with a buck, but nobody saw the service. That is useful information, provided the record says exposure rather than inventing an exact mating date. The same distinction matters when two bucks were present or a later veterinary estimate changes your planning window. Creatures lets you record breeding events and track […]
A goat that is fed well, wormed sensibly, and never culled will usually live into its low-to-mid teens. Washington State University Extension teaches 10 to 15 years as the average for the species, and the captive-longevity record compiled in the AnAge database puts the verified maximum at 20.8 years, held by one female, with a […]
Set up a farm tour by defining the visit before opening the calendar: who it suits, what guests will do, how many people you can host, what the price covers, and how arrival works. Creatures can turn that plan into dated bookable sessions. The bookable-offering guide shows where to create the draft and finish its […]
