Royce, my buck kid I brought in this year, passed away this morning. He is having a necropsy done as we speak and I should have a preliminary tomorrow. But I am so heartbroken and confused...I thought...maybe if I posted the series of events I could get some guesses and some ideas on how I might handle the situation better if anyone else gets sick? This goat and the doe who showed similar symptoms have not been vaccinated for CD&T. The came from a farm that doesn't vaccinate. The task just...fell to the way side... So, a week ago we got new hay. It's a different cutting, but same farm. It's alfalfa. The goats also get to browse on oak trees, pine, weeds, herbs, flowers. All this stuff they've been on for a while. Nothin new....? So, I switch to the new hay slowly because it's leafier and has more flowers - not so stemy. 5 days ago a few of my kids were coughing. 4 days ago my doe Adelle had congestion, a runny nose, a low temp and looked like she felt very sore. Gave her nutri drench, electrolytes with Bs, flushed fluids into her, penicillin. After 2 days she was doing much better and drinking the fluids from a bottle. She's fine now. Royce started acting sick yesterday. I noticed it around 2 PM. Same stuff. Runny nose, congestion, clearly in pain, low temp. He would also cry when he pooped or peed which were both normal. Same mix as with Adelle - water, nutri drench, electrolytes. Plus the pen. By 9 and 2 treatments he wasn't getting any better and was in a lot of pain. To the vet. Vet gives more pen, thiamine injection, tubes him with bicarbonate and water, gives him banamine and dex. We get home around midnight. He has more energy and is making more noise but still low temp and not doing well. I hang out with him in my garage which is very warm (85 deg) most of the time and I stay with him until he falls asleep - about 2 AM. Up at 7 to check and do another tube and more injections - he is long gone. Any ideas what happened? Vet thinks polio. Certainly a GI issue from the new hay is possible. My oaks are blacks which are considered to not have a toxic effect on livestock if introduced slowly (mine were). I lost a kid on my property earlier this year to type C overeating disease so clearly the toxin is in my soil. Anything else? Thanks everyone for the input. It helps me keep busy while I wait for results and watch my goats out my window for signs of trouble.
