In my previous years of rabbit raising I did not encounter this problem so I'm really puzzled and would appreciate any reponse on possible causes. I've been away from rabbits for awhile so it could be something new and I found out tonight another raiser in my area has had the same problem. I've lost 4 or 5 fryers from 10 to 14 wks of age. They appear to be perfectly healthy then the next day will be sitting with their nose tilted slightly upward then be dead in a few hours or the next day. They have no other symptoms. We butchered a few weeks ago and I couldn't find anything wrong internally with those so I'm really stumped. When I noticed the first one I thought it might be wry neck but the condition didn't progress the fryer was dead the next morning. My neighbor had the same thing happen, he mixed terramicyn (?) in the water bottle for a doe that had the same condition and said she drank for an hour then appeared to be improved the next day and is still alive. This is okay but I'd rather know what the cause is to avoid altogether. I also don't know what the withdrawl time would be for the meat after medication? Well, thanks in advance if you have any ideas.
