PREVALENCE OF GASTOINTESTINAL PARASITIC INFESTATION OF PIGS IN CHITTAGONG DIVISION.

Abstract

A cross-sectional study was undertaken to determine the prevalence of gastrointestinal parasitic infestation of pig in Chittagong division, Bangladesh. Fecal samples were collected randomly from 100 pigs between May and August 2013 and examined by routine coproscopical methods. The investigation revealed that the overall prevalence of gastrointestinal parasitic infections was 49% in the study population. Among different gastrointestinal parasitic infections, occurrence Oesophagostomum dentatum infection was the highest which was 17% in study population. The second most common parasitic infection was caused by Ascaris suum (11%) followed by Balantidium coli (7%). The lowest parasitic infections were also recorded for Hyostrongylus rubidus (4%) coccidian oocyst (4%) Trichuris suis (3%) and Strongyloides ransomni (3%). However, sex specific prevalence exposed that female pig showed more susceptibility to different gastrointestinal parasitic infections. Occurrence of Hyostrongylus rubidus and Balantidium coli were found predominant in female pigs than male pigs. On the other hand, occurrence of Ascaris suum was slightly higher in male group than female but it was not statistically significant (P>0.05). It could be stated that the current investigation was fresh of its type which will be acted as bench mark for further study in this area. Moreover, as it was a limited study where breed and topographical variation, seasonal pattern of the diseases were not included. Hence, it was suggested further extensive investigation on gastrointestinal parasitism to overcome the limitations of the current study which will assist to determine the important predictors related to such parasitic diseases.
