Abstract Purpose This paper proposes a low-cost and low-effort solution for determining the area of corn crops damaged by the wildlife facility utilising field images collected by an unmanned aerial vehicle (UAV). The proposed solution allows for the determination of the percentage of the damaged crops and their location. Methods The method utilises image segmentation […]

This study aimed to assess the impact of two commercial Saccharomyces cerevisiae strains (CHY1 and CHY2) on the intestinal health and performance of weaned piglets challenged with enterotoxigenic Escherichia coli during the nursery phase. One hundred ninety-two piglets with an average weight of 6.70 ± 0.92 kilograms were allocated in a randomized block design to

Gallbladder mucocele is characterized by hyperplasia of the gallbladder epithelium, increased mucus production, accumulation, and densification of the bile content, which can lead to biliary obstruction, necrosis, and rupture of the gallbladder wall. Its finding may be accidental or related to symptoms. A retrospective study (2016-2019) was carried out based on abdominal ultrasound examinations in

Cats are susceptible to S. aureus, which mainly colonizes the nose and ears of these feline species. Otitis externa in cat ears is one of the illnesses produced by S. aureus in animals. Antibiotic therapy for affected animals is the conventional treatment for infections by S. aureus. Antibiotic use during prolonged treatment and given at

This study evaluated the effect of diets containing low levels of soluble and insoluble fiber sources on performance, diarrhea score, chemical and physical characteristics of feces, and behavior in weaning piglets. Thirty-six weaned piglets of 30 days of age with an initial body weight of 8.8 kg were distributed in 36 pens using a completely

This publication reports on a rabid dog in São Paulo city, Brazil, with the AgV3 variant of rabies virus related to vampire and fruit bats, which is of significant importance to the surveillance of rabies in a region where the typical canine AgV2 rabies virus has been eradicated. This publication reports on a rabid dog

Bacteriophages (phages) are small viruses that infect bacteria and represent nature’s most abundant biological entities. After infection, new phages are produced during their lytic reproductive cycle, causing disruption of the bacterial cell and releasing bacteriophages into the environment. Thus, phages have been used as a possible strategy for controlling bacterial infections in several areas, including

Establishing methods and actions to improve performance and reduce changes during physical activity is essential in search and rescue dogs. Studying the changes in search and rescue dogs during working activities and how to correct them can help improve their performance and avoid complications. Six healthy adult dogs, which had participated in search and rescue

Neospora caninum is a parasite that causes considerable loss in cattle production. Understanding its infection mechanisms is essential to comprehend its impact on herds. Cell fractionation and characterization of the fractions could contribute to the selection of proteins and organelles with immunogenic characteristics. Thus, the present study aimed to isolate rhoptry and subcellular fractions of

Ketamine is a versatile veterinary, clinical, and hospital drug. Evaluating the binding parameters of ketamine to total plasma proteins from domestic cats provides necessary information in determining the value of the pharmacokinetic parameter named distribution volume, which is used for the consequent prospection of drug concentrations in clinical trials. This work aimed to evaluate the
