Treatment and control of sarcoptic mange: evaluation of treatment of both the pigs and environment.

Pigs in a herd infected with Sarcoptes scabiei var suis were treated with 20% phosmet at a dose rate of 20 mg/kg body weight. In one of the groups the environment was also treated using 2% trichlorphon. Post-treatment clinical examination and parasitological evaluation of skin scrapings revealed complete recovery by the end of the second month after initial treatment with no evidence of reinfection for a period of five months.
