Search the forums for "circling disease" - you will find many hits.
Here is Scott Heinrich's previous response to a farmer who had the circling disease issue in a fawn:
Listeriosis - caused by the bacteria Listeria monocytogenes, found in soil, water, plant litter, silage and deer's digestive tract. Brought on by feeding silage, sudden changes in kind of feed, parasitism, dramatic weather changes and advanced stages of pregnancy.
Symptoms - Depression, decreased appetite, fever, leaning or stumbling or moving in one direction only, head pulled to flank with rigid neck, facial paralysis on one side, slack jaw, and drooling, abortions.
Treatment - Administration of 2cc Procaine penicillin every six hours for three to five days, then daily for an additional seven days.
(Goat Polio) - a Thiamine (Vitamin B 1) deficiency. From improper feeding, particularly feeding too much grain and too little roughage
Symptoms - Excitability, "stargazing", muscle rigidity, uncoordinated staggering and/or weaving, drunkenness, circling, diarrhea, muscle tremor, head against wall, and apparent blindness. A rapid, involuntary, oscillatory motion of the eyeball. As it progresses, convulsions and high fever may occur, and if untreated, the animal generally dies within 24-72 hours.
Treatment - Thiamine is the only effective therapy, and treatment can result in improvement in as little as two hours, if the disease is caught early enough. Dosage is related to body weight:
Use 500mg/ml Thiamin. Start with a gram (1,000 mg) IM the first dose, then at least 500mg per day for as long as it takes for complete recovery. Give 10cc Penicillin orally, and 10cc SQ at first treatment. Polio can be caused by plant thiaminase, or bacteria that either inhibit production of thiamin in the deer's gut, or consume the thiamin. Since we don't know what the origin is, It is preferred to sterilize the gut, and start over. So, the oral penicillin will kill the bacteria if that is the cause. On the morning of day 2, calf pac the fawn, and give 500mg Thiamin orally, and 500mg SQ. Do not repeat any of the penicillin. If the fawn will eat, feed it. If it can't eat, tube it or drench it with 100cc of Revive, 100cc of water several times a day until it can eat.
