It's basically the same as dog and cat in terms of where to listen for the 4 heart valves and lung fields. The only difference is to also listen for rumen contraction rate and quality in the paralumbar fossa (sounds like a rumble of thunder). You said in another thread you're a veterinarian (and I assume by your 'status' as attending) Did they not teach you this in school? I don't know what Egyptian vet schools focus on, however, so I could be wrong. Did you focus exclusively on small animal?
