1. The relationship between protein content of abomasal digesta and abomasal secretion of acid was studied in sheep fitted with re-entrant cannulas in the proximal duodenum. 2. A close relationship was found between the rate of passage of protein through the abomasum and acid secretion, both after varying the protein content of the rations supplied, and after direct introduction of proteins int...

Bovine lymphoma is a common neoplasm in cattle in area where bovine leukosis virus infection is common. Although the typical form of enzootic lymphoma can be easily diagnosed in clinical setting, lymphomatous tissue can cause non specific signs such as abomasal ulcer, ataxia or clinical signs of heart diseases. The aim of this study was to describe echocardiographic findings in 7 cows with a di...

The journal article titled “Effect of Preoperative Erythromycin or Dexamethasone/Vitamin C on Postoperative Abomasal Emptying Rate in Dairy Cows Undergoing Surgical Correction of Abomasal Volvulus” and written by Dr Thomas Wittek, Kataj Tischles, Imke Korner, Dr Tatjana Sattler, Dr Peter Constable, and Dr Manfred Furll may be relevant to practicing veterinarians in dairy practice. The paper con...

Seventeen cows with right displacement of the abomasum (rda) without abomasal volvulus, nine cows with abomasal volvulus and 10 clinically healthy cows were examined ultrasonographically. A 5.0 MHz transducer was used to scan the eighth to 12th intercostal spaces and the cranial and caudal aspects of the flank on the right side. The position, size and dorsal and ventral margins of the abomasum ...

The distribution of T-cell subsets (CD2, CD4, CD8, and gammadelta) and B cells (IgM) was examined at 3, 6, 10 and 13 days post-infection (dpi) in the abomasal mucosa and abomasal lymph nodes of goats primarily infected with Haemonchus contortus. In the abomasal mucosa a mild (3 and 6 dpi) or marked (10 and 13 dpi) increase of T cells, particularly CD4+ and gammadelta+ lymphocytes, was observed,...

a six years old friesian holestin cow was admitted to the veterinary clinic of shiraz university during.-.the spring. the cow had been anorectic with a reduced milk yield. on physical examination the animal showed increased heart beats and respiratory rate. the rumen was hypomotile and resonance sound was heared on the upper half of intercostal 10th to right flank. distension and displacement o...

BACKGROUND This case report describes the clinical and ultrasonographic findings in a Swiss Braunvieh cow with lymphosarcoma of the abomasum. CASE PRESENTATION The main clinical findings were vomiting in response to eating and melena. The results of serum biochemistry and rumen fluid analysis were indicative of abomasal reflux syndrome. The main ultrasonographic findings were two enlarged lym...

the purpose of this study was to induce abomasal displacement to the left, and to let the undergraduate and post graduate students get used to the ping sounds of abomasum and other clinical manifestations. the procedure was carried out on eight young bulls, they were sedated and a 2 m flexible tube was inserted through the nasal canal into the rumen. by laparo-rumenotomy, 20 cm of the tube was ...

OBJECTIVE To determine the effects of 3 commercially available, orally administered electrolyte solutions (OAEs) on abomasal luminal pH and emptying rate in dairy calves, compared with the effect of orally administered milk replacer. DESIGN Randomized crossover study. ANIMALS 6 male dairy calves (age, 12 to 31 days). PROCEDURES Calves were surgically instrumented with an abomasal cannula ...
