Parasites of Pigs of Bangladesh

Thesis research work was carried out in different places of Bangladesh and pigs from different management system were sampled. Fecal sample examination and visceral examination was conducted for helminth parasites. By fecal sample examination 16 different types of helminth ova were identified. Thorugh visceral examination we were able to identify six species of helminth parasites. We also looked for the prevalence of different types of ectoparasites. The chi-square test or the Fisher`s exact test was used to find out any significant associations between the prevalences of the helminths and the management systems. Where chi-square or the Fisher`s exact test were significant, odds ratios were computed for comparing the prevalence of helminths at different management systems. The significant test of the difference between the means of parasitic load in of the two management systems was performed by two-sample t-test. Three multivariable logistic regression models were fitted for identifying the risk factor (s) that significantly influences the respons variables.
