Application techniques of the 'Productivity Calculator' against the resurgence of Sarcoptes scabiei var. suis

摘要

Today, the USA swine industry still battles mange mites. Recent slaughter plant surveys indicate that 29% of different lots of market hogs observed at random kill shifts will show positive mange lesions. These external parasites not only are putting negative pressure on the performance of swine herds, but they also severely lower infested animals' welfare. The Productivity Calculator provides veterinarians farm specific financial outcomes to help them with producer proposals to eliminate this parasite. The Productivity Calculator allows for the input of real world expectations that veterinarians can use to plan herd management practices for mange elimination. The ability to compare worst case and best-case scenarios, when mange is known to be in the swine population, helps veterinarians support their recommendations.
