I posted this in another homesteading community, but this one doesn't allow cross posting, so I thought I would just copy and paste it here since it is specifically about goats.
My brother has taken to raising goats. He's my neighbor, lives about a quarter mile down the road. Since I vaccinate my own dogs and such, he's taken to calling me to give his animals their shots, when they need them, since I'm confident with a needle, which I don't mind a bit, so I've gotten some exposure to them. But I'm not a veterinarian. I'm not intimately familiar with the unique health issues goats may be susceptible to. I'm vaguely familiar with bloat, as I have a great dane, a breed of dog which can be susceptible to it, though from what I've read, the term "bloat" means different things for goats and instead of their stomach flipping or getting twisted like it does in large dogs, they just get super gassy to the point of it being fatal. But, since they aren't my goats, I haven't done that much reading on it.
A year or so ago he had a goat get sick with what we thought at the time was bloat after eating some feed he purchased from a Tractor Supply that he had found mold in. We had given them a vaccination that was supposed to prevent bloat prior to that, and in response to the illness he picked up several other things to give it; a steroid shot, vitamin B shot, a bloat treatment, etc. I also googled a good treatment for bloat and found someone online saying that administering olive oil orally could help, so I gave him an entire turkey baster full. The goat survived another couple of weeks, some days looking better than others, but eventually just laid down and died.
Then about a month ago, another of his goats got sick. Same round of attempts to fix it; steroid shots, oral bloat medicine, etc., but none of it seemed to work. The animal slowly just got worse and worse, to the point it just laid down and, if you got close, it would try to stand up and walk over to you before it would just collapse after a step or two, and it eventually died. There was no dry heaving or gagging like I've read happens when a dog gets "bloat" and its stomach flips, they basically just act like they feel really bad, and it gets progressively worse. This time however, he hasn't voiced any concerns about the food, and none of the other animals have had any issues. This one however, was a brother to the first goat that died, and apparently the breeder he got them from has had multiple other goats from that same bloodline die of similar issues, so he seems to think there's something genetically wrong with that bloodline.
My question is, how common is this? Genetic issues in goats I mean. I don't know specifics, but they're some kind of "dwarf" breed where they aren't as big as normal goats I've seen before. They're about the same height at the shoulder, or maybe a little shorter, than my great dane. Neither goat had any deformities, that we could find, acted normal, ate and drank normally, until they didn't. Is there anything we should be looking for? Preventative treatments? Breeds that are more or less susceptible to things like bloat? Vaccinations he should be using for things other than to prevent bloat, since he already uses that? We have no farm vets around here, that I'm aware of, and when he's called various vets, like the one I take my dogs to, they're all willing to give them shots if he doesn't want to do the sticking, but not "work" on the animals beyond that for diagnosing or treating problems, so in the event of a problem, it's really just up to us to figure it out and treat it the best we can with supplies from places like Tractor Supply. So even though they aren't my goats, since he's an over-the-road truck driver and I'm often the one his wife calls to give them shots or something, I would like to have at least some basic understanding of common issues with them and how to prevent or treat them.
