Abstract

The study was conducted to evaluate the efficacy of Spinosad as an ectoparasite control in laying chickens. Three individual houses of layer chickens from a commercial layer farm with lice and mite infestation were randomly assigned to three groups: control, low dose and high dose. Initial lice and mite counts were determined one day before treatment. A total of 20 chickens from each house were randomly selected and subjected to lice and mite collection every week for nine weeks after spinosad application. Body weight and production parameters were also recorded weekly. Two species of lice, Menopon gallinae and Lipeurus caponis, were identified during the experiment. Megninia cubitalis was the sole species of mite identified throughout the trial. Results of spinosad effectivity trial showed that both low and high dose treatment were highly effective in reducing lice and mites count. The average percent efficacy of spinosad against lice was 96.95% and 99.28% for low dose and high dose treatment groups respectively. The average percent efficacy of low and high dose treatments for mites was 53.61% and 61.66%. Production parameters such as percent egg production and percent mortality was not improved with ectoparasite control.
