Abstract
Mites cause significant losses on poultry farms. The prevalence of poultry red mite (Deramanyssus gallinae) is significant on poultry farms where it causes dermatitis, irritation, anemia, a drop in egg production, but also mortality. Previously chemical substances were commonly used for mite control, but because of the development of resistance and residues in poultry products, they have been abandoned. Due to high mite infestations on farms, novel products, based on essential oils, silica oxide etc., were used, but without prolonged high effectivity. In this research, we monitored a layer hen flock after treatment with the novel product fluralaner. The product was used according to the manufacturers’ recommendation in a dose of
0.5 mg per kilo via drinking water, twice, with a 7 day interval. Infestation was monitored using paper traps, before and after the treatment, as well as the laying rate. The results showed a significant drop in mite count in traps until 9 days after treatment and the disappearance of mites from the building. The laying rate was compared to the previous flock, and the results showed a significantly higher average laying rate in the treated flock. Hematological parameters should be further analyzed to determine the effect of therapy on the dynamics of the restoration of physiological values.
