trapped air in gullet? sounds like he needs to burp!

[parsley]

my boy sometimes comes in from the field and I can hear that there is air in (I presume) his gullet. It burbles up and down and makes him grunt a bit and cough and goes on for ages. he was fine this morning but then had a big drink from thr trough and then one from the river and since then he has the same problem. He looks a bit unhappy but is not colicking.

Does anyone know what causes it, is it a problem beyond making him a bit unhappy and how can I help him clear it?

Thanks for any ideas

You say he's had it for a while?

Have you not asked the vet?

Sounds abit like broken wind or COPD.
