The CDT vaccine will not help her. First, it takes about 2 weeks to take effect. Second, she doesn't have her own immune system to process it. Mother passes on immunity whether the CDT shot is given or not. Not to mention they pass on immunity for way more things than just CDT.
She is gone, last night she passed. Sorry it took so long to get back to you guys. I did try giving the bose and b12 complex again. She had been eating well all day up until her last 2 hours where she suddenly went downhill. I had tried the honey on the gums earlier that day, but I didn't think of the cayenne and I probably should have tried that again. There are barely any goat vets in my state (last time I needed a vet for my goats my vet was swamped and I called every vet I could find on Google within my state and there were none within a 2 hour drive), and i live in a small town. My parents were at work, and I only have my learners permit (2 months until I am 16) so I couldn't drive even if I did find a vet. She had already had tr he vitamine b complex shot. I forgot to check her eyelid coloring.
So very sorry for your loss. I would call your vet and ask who is on back up for you to use if they are not available. I've run across this a time or two, and it's so hard to try to help when none is available. Hugs to you.
