OBJECTIVE This study aimed to report the impact of production practices and sanitary management on the prevalence of Neospora caninum (N caninum) and bluetongue virus (BTV) in Creole goats from the tropical dry forest of Utcubamba, Peru. METHODS 354 blood samples were obtained from male and female goats of diverse ages reared under an extensive productive system. The diagnosis of N caninum and BTV was conducted through a commercial ELISA kit (iD.vet) with readings taken on a Bio-Rad iMark microplate reader at 450 nm. Additionally, a survey was conducted with 18 goat producers to categorize them based on social, technical (production, health, reproduction, nutrition, and infrastructure), environmental, and economic factors. RESULTS The overall seroprevalence of N caninum and BTV in goats was 6.21% and 7.06%, respectively, Notably, group II farmers had the highest prevalence rates at 7.69% for N caninum and 23.08% for BTV. This group comprises producers with fewer than 21 goats, while group III includes 14.3% of producers with over 60 goats and better infrastructure. CONCLUSIONS This study confirms the presence of N caninum and BTV in goats of Utcubamba, Peru. Group II displayed the highest prevalence rates, suggesting that herd size and management infrastructure influence disease prevalence. CLINICAL RELEVANCE In the tropical dry forest of Utcubamba, inadequate management of N caninum carrier agents (eg, nondewormed dogs) heightens transmission risk, while the tropical climate supports BTV vectors. Effective diagnosis and health management strategies, including vector control and biosecurity practices, are crucial for ongoing herd health monitoring

Bovine fascioliasis in Peru is highly prevalent in almost all regions; however, there are few studies about its prevalence in the region of Amazonas. This research aimed to determine the prevalence and risk factors associated with fascioliasis from four livestock basins in the Amazonas region. A total of 941 bovine feces samples were analyzed and a prevalence of 52% was found. The highest prevalence was registered in females (53.9%), crossbred (58.6%), and producers with less than 50 animals (54.40%). The highest risk factor was for Brown Swiss (2.1), crossbreeds (2.4), heifer (4.1), females (1.4), and bovine that drinks water from streams (2.5) and waterhole (2.4). With the principal component analysis, 5 groups were identified, where the first explains that the area of the farm and the number of animals are related to the prevalence of fascioliasis. Group five indicated a relationship between the drinking water source and the breeds with the highest prevalence of fascioliasis. The results show that there are high prevalence and risk factors that affect livestock productivity and welfare. For this reason, there is a need to improve veterinary and animal health support, as well as training in livestock management, providing adequate sources of nutrition, and improving drug administration.
