Has anyone else had experience with this. Bottle fed calf a few months old [ not mine but I'm looking after it] started to go rigid and flat out head back, rigid legs when walking and excessive nervousness, excitability esp to the touch, unable to rise unassisted and grinding teeth , starting to spasm. Was treated initially as if it was tetanus and then the next day had a vit B1 injection incase it was Ccn and seemed to come out of it within 24 hours after that and has made a great recovery in a week even had a wee trot outside with her tail in the air and she's looking great. She had had joint ill so thats why I thought it was tetanus . I had never heard of this so just wondered if anyone else had seen it and thought id put this on here for anyone looking for reference to it. This time last week I was about to get her put down if she had worsened but she came out of it completely
