Haematopinus suis(H. suis) is a common ectoparasite of pigs and is economically important worldwide. H. suis is responsible for anemia and poor feed conversion rate that lead to poor growth in pig husbandry. This study assessed the prevalence and risk factors of H. suis in pigs through a cross-sectional survey in Busogo sector of Musanze district. Fifty-five (55) pigs, representing 10% of 555 pigs from 20 farms, were examined physically for the presence of H. suis, and a total number of 559 H. suis were collected from them in Busogo sector of Musanze district. Data were analyzed using the Statistical Package for the Social Sciences (SPSS). Results showed that out of 55 pigs, a total number of 35 pigs (63.6%), were found infested with H. suis in Busogo sector of Musanze district. The infestation by H. suis was associated with the farming system, animal breeds, animal’s category, sex, pig hygiene, and piggery hygiene. Results showed a high ( P  < 0.05) prevalence in pigs reared in the intensive system (91.4%), whereas large whites were the most affected breed (60%). The prevalence of H. suis varied significantly ( P  < 0.05) among sexes, and females were the most affected (60%). Results related to pig hygiene revealed that all farmers were practicing washing skin three times per week, whereas only 60.0% of them were removing the bedding in their piggery. The study concluded that H. suis is present and remains a problem in the study area. Therefore, the study recommends to create farmer’s awareness on the disease in pigs and its impact through training. Researchers should continue further studies on H. suis prevention with appropriate pig husbandry and management practices and the efficacy of acaricides used.
