Comparison of valnemulin and lincomycin in the treatment of digital dermatitis by individually applied topical spray.
This study was conducted to test and compare the efficacy of the topical treatment of digital dermatitis using a new antibiotic valnemulin against topical treatment with a solution of lincomycin. Twenty four cattle with digital dermatitis was divided into two equal groups (n=12) and were assigned to the following treatment; treatment 1 involved the topical application of 25 ml solution containing 0.6 mg lincomycin/ml (Upjohn); and treatment 2 involved the topical application of 25 ml solution containing 100mg/ml valnemulin (Novartis). There was no significant difference in the proportion of cows without lesions at the end of the study. The cure rate for treatment 1 was 6 of 15 lesions, while that for treatment 2 was 5 of 18 lesions. The results from this study proved that treatment with either valnemulin or lincomycin showed significant improvement in the digital dermatitis within 14 days of the first treatment. The test product valnemulin, was as effective in treating digital dermatitis as compared with lincomycin.
