Fluralaner is an acaricide and insecticide from the isoxazoline family, proven to be highly effective in combating red mite (Dermanyssus gallinae) infestations in chickens. This parasite, known for negatively affecting the health and welfare of poultry, can now be efficiently controlled through the administration of fluralaner via drinking water.
Fluralaner acts as a potent inhibitor of the nervous system in arthropods, specifically antagonizing ligand-gated chloride channels such as GABA and glutamate receptors. This action disrupts the mites’ functioning, eliminating them and halting their ability to reproduce. The activity against mites begins within 4 hours after the parasites feed on treated chickens. Furthermore, egg production in female mites is interrupted for up to 15 days following the first application.
Fluralaner is administered orally, mixed into the chickens’ drinking water, and applied in two doses with a 7-day interval between each. After this cycle, a 3-month pause should be observed before starting a new treatment. This protocol ensures continuous and effective control of red mite infestations.
The results of fluralaner treatments not only eliminate mites but also significantly improve the welfare of the chickens.
Key indicators of improvement include:
• Decreased nighttime activity in chickens, associated with the presence of mites.
• Reduced head scratching, shaking, and excessive preening of feathers.
• Lowered blood corticosterone levels, a hormone related to stress.
Safety studies have shown that fluralaner is safe for use in laying and breeding hens, even during egg production periods. This is crucial, as it ensures continuous production without compromising the health of the birds or the safety of consumers.
To ensure food safety, appropriate withdrawal times have been established following fluralaner administration. For the meat of treated chickens, the withdrawal period is 14 days, while for eggs, no withdrawal time is required, allowing for their immediate consumption without health risks to humans.
In conclusion, the use of fluralaner in chickens not only effectively combats red mite infestations but also enhances the overall welfare of the birds. With proper and safe treatment, producers can keep their chickens healthy and productive, while also ensuring the quality of the products derived from them, including both meat and eggs.
