The identification of structures and conditions responsible for right side tympanitic resonance (ping) in adult cattle

In review of the case records of all cattle greater than or equal to 2 years of age admitted to the Large Animal Hospital of the New York State College of Veterinary Medicine in a 3-year-period, 366 were identified as having areas of right side tympanitic resonance (ping) due to gas distention of intra-abdominal structures. The source of the ping was identified as abomasum in 137 cattle, various segments of the intestinal tract in 157 cattle, and peritoneal gas in 2 cattle. In 70 cattle, no identification was made as to the source of the ping. In 151 (41%) of the cattle with areas of ping, both the clinical and definitive (surgical or necropsy) identification of the source of the ping was recorded. In these cattle, the sensitivity and predictive value of the clinical identification were determined for each structure. The sensitivity and predictively; for cecum and/or ascending colon, the sensitivity and predictive value were both 87%. Of all cattle in which a right side ping was recorded, the principal final diagnoses were: left displacement of the abomasum (116), right displacement of the abomasum (77), abomasal (and omasal) and volvulus (60), other gastrointestinal conditions (73), nongastrointestinal conditions(40).

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
