[QUOTE="Anonymous, post: 12499"] I've seen seizures in cattle from a few different things. Lead poisoning, rabies, salt poisoning, polioencephalomalacia, tumours, electrolyte imbalance. You didn't mention if on their exam they noted any residual neuro deficits or abnormalities. If he had nystagmus, a central lesion is definite. (polio, rabies, tumour, poisonings, not 'lytes) Not all of these things will cause seizures which will initially drop them permanently. If Listeriosis causes the seizure, they're down and that's it in my experience, so that's out. Polio is a deficiency of thiamine, but excess of other nutrients or longterm use of a thiamin analog can cause. Salt poisoning would have been made worse by the drinking, so that's unlikely. Rabies--you have to judge the risk. Here in Ontario, it's always on the list. Lead poisoning--head pressing and blindness. Liver/kidney dz can really only be determined by bloodwork or PM findings--remember lepto can trash kidneys and flukes can nail that liver. (If I remember, you're at high altitude in "high desert" kind of conditions, so flukes are unlikely but I've got to mention them. We don't have them in my area but...) I'm heading to Disneyworld with my kids today for a family vacation, so I won't be able to answer again for a while--sorry! I'll check in again when I get back even though it'll be too late to help you... V [/QUOTE]
