PREVALENCE OF FASCIOLIASIS IN SMALL RUMINANT AT SADAR UPAZILA OF DINAJPUR

Abstract

Fascioliasis plays an important role of major constraints to small ruminant production in Bangladesh. The study was conducted to investigate the prevalence of fascioliasis in small ruminant at sadar upazila of Dinajpur, Bangladesh during January to June 2019, using history, clinical signs, physical and coprological examinations. A total of 106 faecal sample were collected including 80 goat and 26 sheep sample from different area of sadar upazila of Dinajpur and the sample was considered as study population for the present study. Out of 106 sample 22 sample found positive and Overall prevalence of Fascioliasis was 20.75% whereas in case of goat it was 20% and 23.07% in sheep respectively. The age of the study population were divided into three groups i.e. young, adult, and old and their prevalence (%) of fascioliasis were found 15%, 20.58% and 23.07% in goat and 20%, 22,22% and 25% in sheep respectively. According to this study the highest number of positive fascioliasis was found in female goat, out of 45 female goat 10 were found positive and overall prevalence was equivalent to 22.22%%, while out of 35 male goat 6 were found positive and overall prevalence was equivalent to 17.14%. In case of sheep the highest number of positive fascioliasis was found in female, out of 14 female sheep 4 were found positive and overall prevalence was equivalent to 28.57%, while out of 12 male sheep 2 were found positive and overall prevalence was equivalent to 16.67%. In case of goat the higher prevalence of fascioliasis was recorded in poor animal 35.48% followed by healthy 10.20 %. In sheep the higher prevalence of fascioliasis was recorded in poor animal 33.33% followed by healthy 17.65%. The results indicate small ruminant of sadar upazila of Dinajpur area are very much susceptible to fascioliais. To control the disease in this area, appropriate preventive control strategies have to be designed to reduce the impact of the disease on small ruminant.
