MamaDee the link to GoatWorld tells all about the goat polio. It says this if you didn't read it: If you caught it soon enough and started treatment you should starting seeing signs of improvement in as little as two hours, if the disease is caught early enough.
Here are the signs of goat polio: Symptoms - Excitability, "stargazing", uncoordinated staggering and/or weaving, drunkenness, circling, diarrhea, muscle tremor, head against wall, and apparent blindness. As it progresses, convulsions and high fever may occur, and if untreated, the animal generally dies within 24-72 hours. Goat polio has all kinds of signs. A goat may have a few or all it just depends how bad. I know because I had a goat a long while back had that and lost her.
Can improvement be this gradual you ask? The answer is YES.
Goat Polio sometimes is hard to fight but just hang in there. When my goat had this problem she had these signs: uncoordinated staggering and/or weaving, drunkenness, circling, diarrhea head against wall, and apparent blindness. She never had a temp some have it some don't. What happen to me I didn't catch it in time so I lost her but believe me now I keep all types of things on hand just incase.
Good Luck with your goat.
