Myotonic goats have a condition, called myotonia congenita, which causes muscles to stiffen when the animal is startled. This happens to varying degrees. Sometimes the goats remain standing, and other times they fall over. The condition is inherited and causes the goat to be more muscular than other breeds. The breed goes by several different names, Fainting goat, Wooden Leg goat, Stiff Leg goat, Nervous goat, and Scare goat. The breed has a very distinct head and body conformation. Because of the myotonic condition these goats are easier to fence than most goats. The breed originated in Marshal County, Tennessee, in the early 1800's when a farm worker named John Tinsley showed up with three does and a buck that were myotonic. Local people believed he was from Nova Scotia, but they didn't know for sure. When Mr. Tinsley left, a year later, he sold his goats to his employer, Dr. H. H. Mayberry. Dr. Mayberry propagated the goats and did extensive research on them, but he could find no such breed of goat anywhere in the world. There are two breed associations that register Myotonic goats, the Myotonic Goat Registry (http://myotonicgoatregistry.net) and the International Fainting Goat Association (http://faintinggoat.com.) Their web sites have detailed descriptions and pictures of the goats and breeders' directories with contact information."Tennessee Meat Goat" is a registered trade mark owned by Suzanne Gesparotto, Onion Creek Ranch, for her special line of Myotonic goats and "TexMaster Meat Goat" is her trade mark for her line of Myotonic/Boer crosses. More information on these lines of Myotonic meat goats can be found on the web site of Bending Tree Ranch in Arkansas.
