Hello all! Yesterday and today we had our first experience with goat illness that ended in death unfortunately. We have had Nigerian dwarfs for 4 years and have never dealt with any sort of illness (luckily). 3 weeks ago we brought home our first ever adult doe (we have only ever purchased kids or kept our own from our does). She and her herd tested negative for Johnes/cl/cae (sorry if I got the abbreviations incorrect). I also brought home another doe from the same herd. Both UTD on vaccinations. They were kept together separate for 2 weeks and seemingly completely healthy. Upon arrival I de-wormed, BoSe, and probios. They are fed alfalfa and some grains with minerals. On occasion beet pulp for treats. The same thing the last owner fed them. Yesterday morning, I let the goats out and all was usual. By afternoon, I noticed she had scours. Treated her with dewormer, corid, electrolytes, and biomycin 200 I keep on hand incase a doe has a difficult labor (admittedly I’ve never had a need to administer biomycin, so it was my first time but I feel that I did it correctly). Checked on her that evening. Still had scours but was interested in dinner and overall seemed ok. No fever. Checked on her at 2am and same. Went out at 630 and she had taken a turn. Labored breathing, crying, and hardly able to stand. 98 degree temp, so I knew it was probably too late. But I called the vet who came immediately. By the time he arrived, she was taking her last breaths. He still gave her the shot to put her down at my request (sorry, I don’t know what that is called) because I couldn’t stand to see her suffer another second. The vet is at a COMPLETE loss as to what could have happened. Doesn’t sound like pneumonia, parasites, or coccidia because of how quickly it all happened, and hard to say it’s bacterial because she never had a fever. Literally no clue as to what could have happened. He inspected every single one of goats in my herd at my request (gotta love that bill), and all seem fine. All have pebbled stools. He suspects it might be something congenital, but can’t say for sure unless we take her for an autopsy (which honestly isn’t realistic for us to do). I am a complete basket case at this point and extremely concerned about the rest of my herd. I’m checking on them all hourly and taking temps constantly. I contemplated bringing them all into the house to keep an eye on them but my husband said no. So I told him I’ll go sleep with them outside. Lol. But I will seriously probably check on them every hour through the night. Has anyone ever experienced a decline this quickly? Or have ANY clue to what may have happened (yes, I understand it would just be speculation)? How long should I be a lunatic for about all my other goats until I can take a deep breath and be confident they won’t all fall ill also?!?! I am just beside myself right now. Any advice would be appreciated.
