To contribute to the management of gastrointestinal parasites in small grazing ruminants in Cameroon, this study was conducted in the urban and peri-urban areas of three districts in Ngaoundere, a city in the Adamawa region. The objective was to evaluate farmers' knowledge, attitudes and practices regarding the management of this pathology. A total of 385 individuals were interviewed using a semi-structured questionnaire, and 259 of these were selected for the study. The results of the survey indicate that more than half of the farmers in Ngaoundere 2nd had good knowledge of gastrointestinal parasites, with an average score of 87%, whereas the lowest level of knowledge was found in Ngaoundere 3ird, with an average score of 13.4%. Attitudes were more harmful in Ngaoundere 1rst, with a score of 28.7%, than in Ngaoundere 2nd (8.7%) and Ngaoundere 3ird (6%). Ngaoundere 3ird had the most harmful practices (a score of 70.1%), followed by Ngaoundere 1rst and Ngaoundere 2nd (scores of 24.5% and 10.9%, respectively). Certain demographic parameters, such as level of education, age, and years of experience, influence farmers' levels of knowledge, attitudes, and practices. This study highlights the need for continuous training of farmers in the proper management of PGI and regular awareness-raising among farmers about disease management on their farms, as well as informing them about the silent evolution of anthelmintic resistance related to the misuse of veterinary drugs.
