Abstract/ Executive Summary:

The digestive tract of Mongoose consist of oesophagus, stomach, duodenum, Jejunum, ileum, caecum, colon and rectum. Accessory digestive organs includes teeth, tongue, salivary glands, liver, pancreas. Among them liver and pancreas were studied well. Oesophagus was straight tube with a length of 12.3 cm and diameter at cranial and caudal portion was 6.2 mm and 4.7 mm respectively. Respiratory system of mongoose consists of nasal cavity, larynx, trachea and lungs. Trachea was 8 cm long tube consisted of incomplete ‘C’ shaped cartilaginous ring in which incomplete part meet face to face at the dorsal aspect. The cranial and caudal part was 5.16 mm and 4.60 mm diameter respectively.

Program Area: Animal Health and Management

Commodity: Animal

Objectives:

To study the anatomy of digestive and respiratory system of mongoose, which will be a platform for better understanding of physiology, pathology of diseases and subsequent application in clinical examination and surgical intervention if needed.

Methodology:

An adult male Indian grey mongoose (Herpestes edwardsii) was brought in Sahedul Alam Quadery teaching veterinary hospital, Chittagong for surgical treatment but it was found clinically dead. Before post mortem examination species name, body weight, body length, tail length, external features were recorded in hospital case record sheet. Keeping in dorsal recumbancy, a longitudinal incision was made at the ventral midline from pharynx to the pelvic inlet. Thus organs were examined sequentially without any damage or distortion. After thorough post mortem examination it was subjected to anatomical measurement in Anatomy laboratory of the same University. Different views were examined to describe the organs. Length of coiled portion of the respective organ was measured by thread placing on along the long axis of the tubular organ. Circumference was taken with full of content of the organ. Diameter was measured by using slide caliper (0-150 digital caliper, Shinko Denshi Co. Ltd, Japan). Tracheal length was measured from last laryngeal cartilage to the tracheal bifurcation. Each lobe of the lung was studied well by removing the loose attachment within them. For nomenclature Nomina Anatomica Veterinaria, 1994, 4th edition was used.
