What do I do if I have the cow in dorsal recumbency and I cannot hear a ping with my stethoscope?
Apply pressure in front of the cow’s udder. You might even let a person stand on the cow’s belly. If the cow has a gas filled abomasum, it will move cranial and you should be able to hear the abomasal ‘ping’. Based on our experience, we often trocarize a cow without checking for a ‘ping’. In cases with little detectable gas in the abomasum, and concurrent poor rumen fill due to an off feed diagnosis, the percussion/auscultation of the abdominal wall does not produce much ‘ping’ or resonance. We recommend that you trocarize the cow anyway, but only insert the toggle if gas is then detected.
