This study focussed on the therapeutic management of non-perforating abomasal ulcers in cattle. A total of 442 cattle having gastrointestinal disorders were screened based on the presence of melena and positive faecal occult blood tests (FOBT). Among these cases, only 15 were identified as non-perforating abomasal ulcers and further confirmation was done by serum pepsinogen. Out of this, 12 cases were selected for the study and cattle were divided into two groups, Group II received Inj. Ranitidine @ 3 mg/kg b.wt intramuscular BID for 5 days and Group III cattle received Inj. Pantoprazole @ 1 mg/kg b.wt intravenous, SID for 5 days. The treatment evaluation by clinical improvement, haematology, serum biochemistry, serum electrolytes, rumen chloride, serum pepsinogen, serum NEFA and blood gas changes were performed on day 0 of pre-treatment and day 5 post-treatment in both groups. Pantoprazole @ 1 mg/kg b.wt SID IV for 5 days showed early recovery as compared to ranitidine against non-perforating abomasal ulcer in cattle.

The aim of the study was to document the prevalence and diagnosis of thoracic cavity disorders (TCD) in cattle. All the selected animals subjected to detailed anamnesis; physical, clinical haemato-biochemical, electrolytes, cardiac biomarker, thoracic radiography and ultrasonographic examination were performed. The prevalence of TCD was 0.76%, among these; cardiac disorders (CD) was in 37.0%, lung disorders (LD) in 22.0%, lung and cardiac disorders (LCD) in 22.0% and diaphragmatic hernia (DH) in 19.0%. Highest prevalence of thoracic cavity disorders was recorded in Jersey cross bred cattle (62.0%). More than 3 years of age and pregnant animals were the mostly affected. The most predominant clinical signs was recorded in the order of grunting, dyspnea, abduction of elbow, brisket edema, jugular vein engorgement, jowl edema, rumen hypo-motility and muffled heart sound. Haematology revealed significant reduction of Hb, PCV and RBC. Significant decrease in the mean values of serum TP, albumin, glucose, cholesterol and increases in ALP and AST levels were observed. Significant increase in the cardiac biomarkers (CK-MB, LDH and cTnI) was noticed. The presences of foreign body, DH and pericardial effusion were in radiographic examination. Ultrasound examination revealed anechoic fluid (37.50%), mixed echogenic fluid (18.75%), echogenic fibrinous strands (21.85%) on both of respiratory and cardiac disorders. Comprehensive approaches could facilitate early diagnosis of thoracic cavity disorders, as well as to assess the diseases status and to initiate appropriate therapeutic protocols in cattle.

Background: Canine distemper virus (CDV) affects both white and grey matter in the central nervous system (CNS). It causes demyelination of white matter tracts, which releases myelin basic protein (MBP) into the cerebrospinal fluid (CSF). MBP levels in CSF could therefore indirectly indicate the extent of white matter damage. The objective of this study was to determine MBP levels in the CSF of dogs infected with natural cases of neurologic distemper. Methods: In this study samples from healthy dogs, clinical cases of CDV and stray dogs from in and around the institute were collected for investigation. The infection of the CNS was established by estimating the albumin quotient and, for 16 cases, by histopathology. CSF biochemical parameters were analysed for 35 sero-positive clinical cases of neurologic distemper. MBP levels in samples were estimated by quantitative ELISA. Stray dogs (6 cases) were also screened for this purpose. Result: MBP levels in CSF were significantly (p≤0.05) increased in natural cases of distemper encephalomyelitis and stray dogs relative to controls. Three of the neurologic distemper cases clinically recovered despite high MBP levels, and two stray dogs also had higher MBP concentrations. High CSF MBP may therefore not be a useful marker for predicting the outcome of neurologic distemper.

Background: Accidental electrocution was more common in animals and death was mostly due to shock and cardiac arrest. Survival of animals or humans could be possible if victims receive immediate medical support. Case description: A 3-year-old crossbred Jersey heifer was presented to the Emergency and Critical Care Medicine Referral Clinic of the Veterinary College and Research Institute, Orathanadu, with a history of accidental electrocution by broken high-tension overhead power transmission line during grazing in the paddy fields. The animal was dull and depressed, dark red, and some areas were charred in appearance on the dorsum and limbs. The animal showed difficulty walking due to the electrocution burn injury and was poorly responding to the surroundings. Clinical examination revealed subnormal temperature, polypnea, pale mucous membranes, ruminal atony, and arrhythmias on auscultation. Findings/treatment and outcome: On point of care (PoC) hematology testing, leukocytosis, neutrophilia, and microcytosis were observed. PoC electrolyte analysis revealed hypocalcemia (ionized calcium 0.89 mmol/L), mild hypochloremia, and severe hypokalemia (2.81 mmol/L). PoC biochemistry revealed hypoglycemia (41 mg/dl). PoC elevated levels of serum cardiac troponin (0.33 ng/dl) indicated cardiac damage. Aspartate aminotransferase (1794 U/L), CK-MB (699 U/L) and LDH (6.7 U/L) were also elevated. On PoC urinalysis, proteinuria, myoglobinuria, and glucosuria were observed. Evident clinical recovery, wound healing, and improvement in animal activities were observed. Conclusion: High-voltage electrocution injury is a serious type of accident with the potential risk of multi-organ damage and death. Early diagnosis of electrocution and immediate management enhances the expectancy of complete recovery.

| Mixed parasitic infection is a challenging task in terms of diagnosis and therapy and unidentified cases may lead to life threatening situation in humans and animals causing zoonosis. Here author report a case of a four month old male large white Yorkshire pig with the history of inappetence and chronic diarrhoea which is hemorrhagic in nature at its lateral stages of illness. Clinical, faecal examination and Egg per gram (EPG) studies were done to identify the presence of parasites. Large numbers of motile Balantidium coli, motile Ascaris suum larva and Ascaris suum eggs were seen under microscopic examination. EPG studies showed high counts for Trichuris suis, and Ascaris suum. Hematology revealed anemia and leukocytosis. Medical management consisting of fluid therapy, anti parasites and supportive therapy were given and pig was recovered uneventfully two weeks of treatment.

Data on Production diseases assessment in Indian dairy cattle is less. The objective of this study was to assess the Non-esterified fatty acids level in three different small holder farms of Cauvery Delta region of Tamilnadu. Sixty cross bred dairy cattle were selected at different levels of lactation in the three farms. Serum samples were analyzed for non esterified fatty acids (NEFA). Mean ± standard deviations of the values were arrived and the data were statistically analyzed. NEFA values of early, mid, late lactation, Far off dry and close up dry cows were 0.39±0.09, 0.24±0.03, 0.19±0.03, 0.18±0.03 and 0.23±0.03mmol/L, respectively. No significant variations were recorded in between the farms. Cows at early lactation had higher NEFA concentrations where as lowest concentrations was observed in Far off Dry cows.

Ultrasonography helps in early diagnosis of large animal digestive disorders especially in cattle with empty rectum and also to initiate early therapeutic and surgical management. The study was undertaken to elicit GI disturbances in cattle at TVCC, VCRI, Orathanadu during 2015-16. Animals with history of absence of feces and or empty rectum were selected for this study. In total twenty nine cattle were found to be affected with various GI disorders. The incidence of GI disturbances was more (65.52 %) in cross bred Jersey cow. The common clinical signs were absence of feces (65.52 %), anorexia (58.62 %), scant/tarry/mucous coated foul smelling feces (34.48 %), arched back (24.14 %) and abdominal distention (24.14 %). All selected 29 animals were subjected to abdominal ultrasonography which revealed peritonitis (31.03 %), paralytic ileus with peritonitis and pericarditis in each 10.34 %, uroabdomen, intussusceptions, caecal dilatation, abomasal dilatation and peritonitis with intussusceptions in each 6.90 % and diaphragmatic hernia, reticular abscess, omasal impaction and peritonitis with pericarditis in each 3.45 %. Based on this study, clinical and ultrasonographic examinations were found to be a useful tool for the diagnosis of GI disorders of cattle with empty rectum.
