UPDATE ON IVOMEC~(R) FOR SWINE HERD MENGE/LICE ELIMINATION (HM/LE) PROGRAM

摘要

Ectoparasites such as sarcoptic mange mites, Sarcoptes scabiei var. suis, and pig lice, Haematopinus suis, have a substantial negative effect on productivity. The mite S. scabiei var. suis, the cause of sarcoptic mange, is the most harmful ectoparasite affecting swine worldwide. Even though pigs experience reduced weight gain and feed efficiency, clinical signs of mange are often viewed as normal because there is no mortality. Producers often tolerate the disease, because of the covert nature of thelosses.
