Figure Lengend Snippet: Facility design for the dose confirmation study. Cages separated by treatment group (Control or Medicated) to reduce possible cross-contamination, and each treatment group organized into four cage blocks with four cages in each block (Control: 1A–4D; Medicated: 5A–8D). Cages A and B were positioned above cages C and D in each cage block, with top and bottom cages separated by a metal shelf. Each cage held four birds with NFM counts on birds balanced across treatment groups, cage blocks, and cages within a block. Care was taken throughout the study to prevent transfer of fluralaner medication or mites among birds in different cage blocks and treatment groups

Figure Lengend Snippet: Facility design for the field efficacy trial. Cages separated according to treatment group (Control: 1–200; Medicated: 201–400) with two birds in each cage. Care was taken throughout the study to prevent transfer of fluralaner medication or mites between treatment groups, though poultry houses on this farm were open-sided (no walls) allowing access by wild birds, which were noted to occasionally rest on cages or feed troughs

Figure Lengend Snippet: Mean number (± standard error, SE) of mites on layer chickens (~ 20 weeks old) in the field efficacy trial. Chickens received either untreated drinking water or fluralaner administered in drinking water at 0.5 mg/kg body weight on day 0 and day 7 (treatment dates indicated with grey arrows). Significance indicated at P < 0.0001 (***) or not significant (NS)

Egg production per treatment group (400 layers in each group) was recorded daily from day −4 through day 28 post-treatment. Fluralaner was administered to Medicated group birds on days 0 and 7 as indicated by arrows
