Evaluating the efficacy of two footbath concentrates to control digital dermatitis in freestall dairy cows using a non-inferiority study
American Association of Bovine Practitioners Conference Proceedings(2023)
摘要
Digital dermatitis (DD), an infectious hoof lesion, is prevalent in U.S. dairies and compromises cow health, welfare and profitability. Footbaths are the main form of DD prevention and control. Understanding the comparative efficacies among commercial footbath products in preventing and controlling DD cases within a herd is necessary to provide farms with the information required when selecting a product for use. Digital dermatitis (DD), an infectious hoof lesion, is prevalent in U.S. dairies and can rapidly become endemic to a herd if not proactively controlled, compromising cow health, welfare and profitability. Footbaths are the main form of DD prevention and control. Understanding the comparative efficacies among commercial footbath products in preventing and controlling DD cases within a herd is necessary to provide farms with the information required when selecting a product for use. Our primary objective was to determine if a commercial footbath concentrate (Healmax®) was non-inferior to a copper sulfate concentrate in the prevention of new cases of digital dermatitis (DD). As a secondary objective, we sought to investigate the comparative efficacies of the 2 products in the control of chronic DD cases.
