ABSTRACT
PARASITIC SKIN DISEASES LICE (PEDICULOSIS) DEFINITION/OVERVIEW Infestations with lice are found in all cattle-producing countries and can cause production losses due to reduced feeding time and damaged hides (473). Louse populations are highest in cattle kept indoors during the winter months and those in poor body condition, rather than the reverse situation where lice cause debility. Heavy louse infestations cause irritation, self-trauma and possibly anaemia and therefore warrant treatment for welfare reasons. The cause of any underlying debilitating condition/ disease must be investigated and corrected. Louse infestations do not present a significant financial concern.
