Ultrasonographic examination of the forestomachs and the abomasum in ruminal drinker calves.

Background: The study investigated the ultrasonographic appearance of the reticulum, rumen, omasum and abomasum of calves with ruminal drinking syndrome.

Methods: In ten milk-fed calves with ruminal drinking syndrome the reticulum, rumen, omasum and abomasum were examined by ultrasonography using a 5-MHz linear transducer before, during and after the ingestion of milk.

Results: The reticulum could be imaged in eight of ten calves before feeding.

Ultrasonography of the reticulum, rumen, omasum, and abomasum in 10 calves before, during, and after ingestion of milk.

The reticulum, rumen, omasum, and abomasum were assessed via ultrasonography before, during, and 15, 30, and 120 minutes after feeding milk to 10 healthy calves. The ultrasonographic examinations were conducted using a 5.0 MHz linear transducer.

Ultrasonography of the reticulum, rumen, omasum and abomasum before, during and after ingestion of hay and grass silage in 10 calves.

The reticulum, rumen, omasum and abomasum were assessed via ultrasonography in 10 healthy female calves before, during and 2 h after feeding hay and grass silage. The evaluations were made using an ultrasound machine with a 5.0 MHz linear transducer.

[Severe inflammation of the muzzle caused by a nose ring in a breeding bull].

This report describes the findings in a bull with severe inflammation of the muzzle and nose attributable to a nose ring. The most striking finding was that the bull continually licked the right side of the upper lip. The muzzle and right upper lip were swollen, hard, reddened and partially depigmented.

[Ultrasonographic findings in a cow with extraskeletal chondroblastic osteosarcoma of the neck region].

This case report describes the clinical, ultrasonographic and pathological findings in a five-year-old Swiss Braunvieh cow with extraskeletal chondroblastic osteosarcoma of the neck region. The cow was referred because of a firm, non-painful swelling, approximately 25 cm in diameter, which was situated mainly on the lower left side of the neck but extended to the right. Ultrasonographic examination of the mass revealed a chambered structure containing echoic material that was separated by hyperechoic septa.
