But I think bloat is different in cud chewing animals and horses also...Daughters horse got the bloat once and it meant a vet visit..
With animals as soon as the gas is released, they are OK. No surgery's needed that I know of, but could be wrong on the surgery aspect with some animals. Just never heard of surgery needed with animals.
Cud chewers have more than one chamber to the stomach..they eat the grass and it goes into one chamber, when they bring it up to chew the cud, it then goes into a different chamber of the stomach...gas can block one of the chambers and it just needs to be released...Horses and dogs aren't cud chewers so for them the bloat is a little different.
My first kidding season on the farm I lost 3 kids to bloat cause I didn't know what they had. The 4th I was able to save...(I wasn't too smart on animals when I started with my flock of goats) You learn fast or everything dies on you :O)
One of my favorite bantys got eye worms. Never heard of that either, I had to finally do a mercy killing on him...1/2 of his head was twice as large as the other half. Found out later what caused it...
My great uncle used to say it was caused by eating too much too green alfalfa(I think). He’d stick an ice pick in the cow’s belly to let the air out. you had to know exactly where to poke the hole. Stinky air and green goop would shoot out. Then the cow would get up and walk away.
