The Flumethrin Applications in Brown Swiss Cross Calves

Abstract

In this study, we aimed to compare dermatological examination findings in the applied skin region following local application of 1% flumethrin pour-on solution at a dose of 1 ml/10 kg. The study was conducted on a total of 50 Brown Swiss cross male calves kept under a half-open feedlot. Their ages ranged from 8 months to 12 months and their weight ranged from 180 kg to 250 kg. Of the calves, 40 calves (Group 1, n=20; Group 11, n=20) received flumethrin solution treatment along the midline of the back from the front of the shoulders to the tail setting. Remaining 10 calves were kept as a control group (Group 111). During the study, calves in groups I and III exposed to direct sun light while calves in Group 11 were kept in the part of the barn with no sun light exposure. At the 1th hour, 1th day, and 7th day following flumethrin application, the applied skin region was examined as clinically. The data were analyzed using One-Way Anova-Tukey. There were no significant differences among groups for the skin thickness and skin lesions (p > 0.05). Based on the clinical findings, we concluded that application of flumethrin pour-on solution at a dose of 1 ml/10 kg does not induce dermatological abnormalities in Brown Swiss cross calves, exposed to sunlight or kept indoors.
