Stryphnodendron adstringens extract associated with the hooves trimming surgical procedure for the treatment of bovine digital dermatitis

Abstract

Hoof care, lesion curettage, and application of 5 % Stryphnodendron adstringens bark extract (S. adstringens (Mart.) Coville) or 3 % copper sulfate on surgical wounds of cattle were carried out in this research. A total of 180 cattle with digital dermatitis were used. They were distributed into six groups of 30 animals each (GI, GII, GIII, GIV, GV, and GVI). In GI and GII, only the sick digit was trimmed; in GIII and GIV, both sick and healthy digits of the lesioned limb were trimmed; and in GV and GVI, all digits were trimmed. During the postoperative period, 5 % S. adstringens extract was applied in GI, GIII, and GV, and 3 % copper sulfate solution was applied in GII, GIV, and GVI. After 60 days of evaluation, the data were analyzed using the Chi-squared test (p ≤ 0.05). Both therapeutic protocols utilizing surgical curettage of the lesions were efficient for treating digital dermatitis. However, when the procedure is followed by the trimming of sick and healthy digits, the healing is optimized and a greater number of animals are rehabilitated.
