Eradication of Lice in Cattle

Abstract

Nafstad O, Grønstøl H: Eradication of lice in cattle. Acta vet. scand. 2001, 42, 81-89 -The purpose of this field study was to develop and evaluate eradication as a strategy to control lice in cattle. Thirty-three herds of cattle were selected and observed during a period of two and a half years. Before eradication, biting lice (Damalinia bovis) were present in 94% of the herds and 27% of the animals. Sucking lice (Linognathus vituli) were present in 42% of the herds and 5% of the animals. These levels were very similar to those reported from other countries in Northern Europe. The eradication strategy was successful in 28 of 33 herds, but lice were still present in 5 herds 3 to 6 months after treatment. Biting lice were present in all these 5 herds, sucking lice were present in 3 herds. During the next 12 months, nine of the 28 herds were reinfected with lice. Six herds were reinfected with just biting lice, 2 herds with just sucking lice and one herd was reinfected with both. There was no significant difference between the 2 louse species regarding the risk of unsuccessful eradication or reinfection. The only significant risk factor for reinfection was either purchase of livestock or use of common pasture, combined with failure in pre-treatment of newly introduced animals.lice; cattle; Damalinia bovis; Linognathus vituli; eradication strategy.

“…Nafstad and Gronstol [ 28 ] mentioned that lice are a significant problem which remains under-estimated among non-treated herds.…”

“…between 0.3792 and 0.6651. Both the median intensity (15.0) and its confidence interval (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23) were the highest in the herd kept at Hany and, exceeded the corresponding values of the entire study population (12; 8-22). The discrepancy index (D) showed a linear correlation with the distribution according to Crofton (1971), i.e.…”

“…In a survey conducted in Pakistan [6], the prevalence of lice was significantly (P<0.05) higher in cattle than in buffaloes: 144 out of 600 randomly selected cattle (24%) and only 113 out of 600 randomly selected buffaloes (18%), kept under conditions identical to those of the cattle, proved to be infected. The prevalence of louse infestation in cattle has been reported by researchers from different countries [11][12][13] have reported varying prevalence rates of louse infestation in cattle in association with differences in the ecological, geographic and weather conditions. Animals kept in closed management systems are not exposed to direct sunlight which favours the survival of lice.…”

The prevalence of louse infestation in cattle has been reported by researchers from different countries [19][20][21] have reported varying prevalence rates of louse infestation in cattle in association with differences in the ecological, geographic and weather conditions. Animals kept in closed management systems are not exposed to direct sunlight, which favors the survival of lice.…”
