This is from Fias Co Farm:
What is bloat?
A goat's rumen is a big fermentation vat which produces carbon dioxide and methane gas These gasses are eliminated by the goat burping and pooting... A goat needs to expel their gas, no matter how rude or funny you may think it may be. If they cannot expel the gas, the pressure builds up and the goat "bloats". When this happens, the left side of the goat will become distended which might even cause difficulty in breathing.
SInce being wide is actually a good thing, how can you tell if your goat is bloating?
When you look at him or her head on, are either of his sides wider than the other? In cases of bloat, the goat's left side will be wider than the right. If both sides are the same size and the goat is showing no signs of distress, it's probably nothing to worry about.
-------------------------------------------------------------
We feed some hay in the morning and the goats eat up some hay and then graze and then lay down and then graze and then lay down and then graze and finally in the evening when it is cooled off, they go out and gorge themselves. We have noticed a total of 2-3 times in the past 4 months or so, what we are calling a bloated goat. I'm going based on the information above - one side is way bigger than the other. We'll have goats in the evening (after gorging) that are fat on both sides - we just figure they have full tummies. Our thoughts are that feeding some hay in the morning will keep them from waking up and gorging themselves in the morning and potentially causing bloat. I just think I shouldn't have to feed some hay in the evening too so they won't go pig out.
