Twenty nine animals (22 cattle and 7 buffaloes) having type 2 abomasal ulcer (AU2) were studied in this prospective investigation, along with a control group (n = 20). Signalment, history, clinical signs, and laboratory alterations were determined. Blood, rumen fluid, abomasal fluid, and fecal samples were collected at the time of presentation. Depressed behavior, anorexia, dehydration, melena, sparse feces, and mushy rumen with substantially reduced or nonexistent motility, tachycardia, and tachypnea were common clinical findings. Colic was observed in 58% of animals. While the neutrophil count was significantly greater, the mean of lymphocytes, hemoglobin, erythrocyte count, and hematocrit were all lower (p < 0.05) than the corresponding control values. In comparison to the control values, the levels of BHBA, NEFA, lactate, bilirubin, BUN, creatinine, LDH, CK, GGT, ALP, and AST were significantly higher but levels of proteins, cholesterol, Na, K, Cl, and calcium were lower (p < 0.05). In comparison to the control values, the other hemato-biochemical parameters did not differ substantially (p < 0.05). The rumen and abomasal pH were within the reference range while rumen chloride concentration was increased in majority of animals. Higher percentage (p < 0.05) of non-survivors showed left shift and toxic alterations in neutrophils than the survivors. As compared to the survivors, the non-survivors had higher (p < 0.05) BHBA, triglycerides, total bilirubin, AST, ALP, LDH, and lactate, and lower (p < 0.05) fibrinogen and calcium. The response to medical treatment was fair, long time survival rate was good, and there was no recurrence. The follow-up period was 28 months. After treatment, both the current and the subsequent lactation's milk production were unaffected., (© 2023. The Author(s), under exclusive licence to Springer Nature B.V.)

The study was conducted to establish the ultrasonographic features of the healthy and impacted omasum in cows and buffaloes. Scanning was done using a 3.5 MHz microconvex transducer. In healthy buffaloes, the omasum could be scanned at the eighth to ninth intercostal space as a round or oval structure having thick echogenic wall with echogenic leaves. Gradual slow movements of omasal leaves could also be seen in real-time B-mode. The omasum appeared to be very clear, large, and close to the transducer at the start of the omasal contraction, and as the contraction progressed the omasum retracted away from the transducer and became very small. In healthy cows the omasum was seen as a crescent-shaped structure with an echogenic wall. The contents of the omasum or omasal leaves could not be visualized. Omasal contractility was not as prominent as in buffaloes. In buffaloes, the impacted omasum appeared amotile, the omasal leaves were not visible, and the omasum as a whole gave a prominent distal acoustic shadow. In cows, the impaction could be diagnosed based on amotile omasum covering a large area on the right side. Ultrasonography was found to be helpful in subjective assessment of omasal impaction but could not aid in diagnosing the severity of impaction.

Eight cows and 7 buffaloes with massive abdominal wall swellings were examined. The aim of the ultrasonographic study was to learn the contents of the abdominal wall swellings. They were divided into 4 groups: Group I (prepubic tendon rupture or hernia), Group II (fibrino-cystic swelling), Group III (abscess), and Group IV (inflammatory swelling). Palpation of the swelling in semidorsal recumbency, needle aspiration, or surgery was used to confirm the diagnosis. In animals of Groups I, II, and III, in the ultrasound, the muscles appeared to separate from the skin at the margin of swelling, thus creating a gap. In this gap, intestines or viscera were seen in Group I, fluid and fibrin shreds in Group II, and encapsulated cavity with uniform echogenic contents in Group III. Intact muscles were followed up to the hernial ring in Group I and throughout the swelling in Groups II and III. From the ultrasound, a gradual increase in the total abdominal wall thickness was observed in Group IV. To conclude, ultrasonography can differentiate hernia from fibrino-cystic, abscess, or inflammatory abdominal wall swellings in bovids. [ABSTRACT FROM AUTHOR]

Aim: Echinococcosis is the major cause of lung and liver cysts in ruminants. This study compared usefulness of radiography and ultrasonography (USG) in the detection of lung and/or liver cysts in sick bovine animals. The study also worked out cooccurrence of lung and liver cysts, and whether these cysts were primary cause of sickness or not. Materials and Methods: This study was conducted on 45 sick bovine (37 buffaloes and 8 cattle) suffering from lung and liver cysts. A complete history of illness and clinical examination was carried out. Lateral radiographs of chest and reticular region were taken. In radiographically positive or suspected cases of cysts, USG of the lung and liver region was done. Depending on the location of cyst and clinical manifestations of the animal, the cysts were categorized as primary or secondary causes of sickness. Results: Using either imaging technique, it was observed that 46.7% of the animals had both lung and liver cysts, whereas 33.3% had only lung and 20% had only liver cyst. Cysts were identified as primary cause of sickness in 31.1% animals only. For diagnosing lung cysts, radiography (71.1%) and USG (62.2%) had similar diagnostic utility. However, for detecting liver cysts, USG was the only imaging tool. Conclusion: The lung and liver cysts, depending on their number and size may be a primary cause of sickness in bovine. Radiography and USG are recommended, in combination, as screening tools to rule out echinococcosis. [ABSTRACT FROM AUTHOR]
