INTERESTING !!! Sometimes you can't believe every published article written by bleeding hearts. I have done the captive bolt pistal to the head, .22 bullet to the head, electricution, and chemical euthanasia at this very same institution at the Vet Med teaching hospital hundreds of times. In the right hands , they work instantly, except the air injection, as well as some common chemical methods mentioned which DOES NOT work. Under your current surcomstances at this time and place, a .22 bullet to the goat's forehead would be the most effective and humane way to go. Good luck.Sorry LS - doesn't look like that will work.

"Unacceptable Methods of Sheep & Goat Euthanasia
Ethical and humane standards of euthanasia DO NOT permit the following methods of euthanasia for sheep and goats: • Manually applied blunt trauma to the head. • Injection of chemical agents into conscious animals (e.g., disinfectants, certain electrolytes such as KCl, nonanesthetic pharmaceutical agents). • Air embolism (e.g., the injection of a large amount of air into the circulatory system). • Electrocution with a 120-volt electrical cord."
