Research on parasitosis was begun on farms in various regions of the Czech Republic with the aim of preparing suitable anthelmintic programmes for the control of roundworms and sarcoptic mange. There are economic losses in pig breeding due to liver condemnation (hepatitis parasilaria) in slaughterhouses. Some breeders asked us for a remedy to this situation Slaughter, including monitoring the liver spots, is both preventive and diagnostic and a method of control parasitic infestation in pig herds. Treatment of the whole herd by addition to the feed is preferred, because the larvae are killed during developing stages. In recent years, some farms have chosen ivermectin for efficacy against mange.
