I recently took in three donkey's that ended up being rescue donkeys. From a seller in PA. She sold me three donkeys. They arrived with no health record, all came down with shipping fever. They all were put on antibiotics for ten days. Two of the donkey's were extremely malnourished. You could see their spines, hip bones and ribs protruding. One of them had long feet which my Farrier was able to take care of. I lost one donkey and the other one is on the fence. Vet did a complete blood count. Vet recommends a senior feed, free choice hay, water and a separate honey water bucket. This donkey remains pretty weak lays down, gets up, and back and forth. He is very stiff when up and weak but is able to shuffle slowly in his stall. My vet believes when the cold weather returned it may have pushed the donkey's over the edge. I have blankets on him and have a floor heater for my barn. I asked my vet if anemia may have set in due to nutritional deficiency. She does not believe so. My third donkey being the healthiest, is doing ok. My sick donkey is Lorenzo. They are miniature Sicilian donkey's. Donkey is eating hay, eating senior grain, drinking water, and has been pooping. He Just remains weak. I have spoken to two separate vets and they both suggest the above level of care. I have also been putting honey and water in a syringe throughout the day. I've also reached out to a donkey rescue and they mentioned: I would have complete blood panels run on the donkeys. Check vitamin E and selenium levels. We have seen several cases of botulism in donkeys of late, so at least mention that to your vet to have in the back of his/her mind. I am not a vet!!! but, in my experience a much longer course of antibiotics is often needed. I know that depends on what the antibiotics are for and which drug is being used.
