dc.description.abstractThe research work was carried out to study the incidence, clinical signs, haematobiochemical changes, endoscopic findings in cattle with oesophageal disorders and to evaluate the effect of sedation on oesophagus in cattle. Twelve apparently healthy cattle were randomly selected to obtain normal oesophagoscopic images along with data of parameters under study. Thirty seven cattle with oesophageal disorders formed the clinical group and were subjected to detailed anamnesis, clinical examination, haemato biochemistry, radiographic and endoscopic evaluation of oesophagus. Incidence of oesophageal disorder in cattle was 2.47 per cent of the various medical disease conditions. Salient clinical signs noticed in oesophageal disorders were salivation, tachypnoea, bloat, regurgitation with extended head and neck, cough, tachycardia, dysphagia and swelling on left side of the neck. Cattle with oesophageal foreign body had highly significant elevation of mean packed cell volume and serum creatine phosphokinase value while there was leucocytosis with neutrophilia in cattle with oesophageal dilatation when compared to that of respective control mean. In cattle with oesophageal dilatation, there was dilatation of oesophagus either in the cervical and / or thoracic part in plain radiograph and retention of barium in the dilated oesophagus in contrast oesophagogram of cervico-thoracic region. In animals with oesophageal foreign body, soft tissue opacity was seen within the oesophagus contrasted by gas. On oesophagoscopy of apparently healthy cattle, oesophageal mucosa appeared light pink coloured, smooth and glistening with submucosal vascular pattern. The oesophagus had longitudinal mucosal folds and were closed together to appear like a star. Upon insufflations with air, the folds got separated and the cardia appeared as a slit. In cattle with oesophageal dilatation, oesophagoscopy revealed dilated oesophagus with feed and / or water and absence of linear folds. Various oesophageal foreign bodies observed during the study period include beetroot, tapioca, cabbage, bone piece, linear rusted iron piece, rope, guava, orange, fish hook, mango and phytobezoar. Majority of the foreign bodies were noticed in the cervical oesophagus. Increased vascularity of submucosal vessels, mucosal ulcers or haemorrhage was noticed through oesophagoscopy in cattle with oesophagitis.en_US
