A STUDY ON CLINICAL INVESTIGATION OF NAVEL ILL IN BOVINE CALVES AT MITHAPUKUR UPAZILA IN RANGPUR DISTRICT

Abstract

The study was undertaken to investigate the navel ill in calves associated with some risk factors. Navel ill is an open wound in the umbilical cord complicated by different bacteria and fly larvae, which is characterized by umbilical inflammation, abscess formation and high temperature. In this study a total number of 25 cases of navel ill of bovine calves were studied at Upazila Veterinary Hospital, Mithapukur, Rangpur from 16th July to 15th September 2012.The study was conducted with the help of a preset questionnaire, clinical examination and observing presenting clinical signs of the patient. In this study the risk factors were housing system, age, sex, breeds, complication of disease and their management at individual level. Result revealed that calves reared on mud floor were found infected at higher rate (72%) than those on concrete floor (8%) and semi-concrete floor (20%). The infection rate was higher at the age of 0-15 days (56%) than 16-30 days (32%) and 31-60 days (12%). On the other hand male calves were found more infected (68%) than female calves (32%). In unhygienic environmental condition the infection rate was higher (84%) than hygienic condition (16%). The development of navel ill from open wound can be prevented by practicing improved hygiene, proper sanitation and control of flies.
