Assessing the efficacy and zootechnical performance in laying hens after administration of a 1% aqueous solution of fluralaner (Exzolt) for treating natural infestation by Menacanthus cornutus.

A brood of laying hens infested with the lice Menacanthus cornutus (Phthiraptera: Menoponidae) evidenced itching, irritation, and damage to their zootechnical performance. A study was conducted to evaluate the zootechnical performance and infestation control using a 1% solution of fluralaner in a brood of white laying hens infested naturally with lice. The experiment was carried out using 10,560 naturally infested chickens divided into 2 groups: a treatment group of animals that received a 1% solution of fluralaner in drinking water, at a dose of 0.
