Objective: This study aimed to assess the prevalence and risk factors of African swine fever (ASF) disease in Benin. Materials and methods: A retrospective study was conducted on 70 pig farms from the Departement of Atlantique and Oueme and also by using the data available from the Directorate of Livestock on the spread of ASF in Benin from 2014 to 2018. The prevalence of ASF was assessed with 106 nasal swabs from apparently healthy domestic pigs and 15 organ samples from dead ASF-suspected pigs. ASF virus detection was carried out by conventional polymerase chain reac¬tion using Qiagen Kit for DNA extraction. Data recorded were processed with SAS software (2006). Results: It appears that ASF is an endemic disease in Benin with the Department of Oueme as the hotspot of dissemination of the virus in the country. The losses due to ASF recorded from 2014 to 2018 are evaluated to 884,850,000 CFA Franc by estimating the average cost of a pig at 25,000 FCFA. A prevalence of 1.89% (CI at 95%, 0.713.49) was recorded for live animals with a positive result in organs from all dead pigs suspected of ASF. Breeding practices related to the sharing of breeding males, scavenging pigs, and non-compliance with biosecurity measures were the risk factors identified. Conclusion: The present study sheds light on the areas prone to the ASF virus in Benin. Moreover, the cross-sectional data recorded on the prevalence of ASF will help to better rule on the spread of the disease. It would be interesting for the Beninese Republic to increase its efforts for ASF control. [J Adv Vet Anim Res 2020; 7(3.000): 464-470]

Objective: The present study aimed to determine the prevalence of bovine trypanosomosis in Benin. Materials and Methods: For this purpose, the blood samples were taken from 932 cattle: 573 from slaughterhouses and 359 from the farms of the targeted divisions. After the blood samples, thick drops and blood smears were made. The capillary tubes filled with blood made it possible to determine the hematocrit in cattle. Results: The prevalence of trypanosomosis in farms (27.02%) was significantly higher (p < 0.001) than that of animals in slaughterhouses (16.75%). In farms, the prevalence was 38.55% during the rainy season against 16.67% in the dry season (p < 0.001). In slaughterhouses, prevalences were 10.99%, 17.58%, and 21.50%, respectively, in Bohicon, Cotonou/Porto-Novo, and Parakou. Hematocrit in slaughterhouses was 24.17% and 31.44%, respectively, in infested and non-infested animals. In farms, this rate was 22.85% in infested animals and 29.31% in non-infested animals (p < 0.05). Young cattle are more vulnerable to trypanosomosis than older cattle. Conclusion: Given the endemic situation of bovine trypanosomosis and its impact on the econ¬omy, this knowledge of the health status of cattle will help out to seek ways and alternatives to reduce the damage.
