Tekuti na farmama peradi uzrokuju znatne gubitke u proizvodnji. Najučestalija je tekut (Deramanyssus gallinae), koja uzrokuje dermatitis, iritaciju, anemiju, pad nesivosti, ali i uginuće. Za suzbijanje su najčešće korišteni kemijski pripravci koji su zbog razvoja rezistencije i rezidua u proizvodima izašli iz upotrebe. Zbog visoke invadiranosti za suzbijanje tekuti na farmama upotrebljavaju se različiti pripravci temeljeni na eteričnim uljima, silikatnim mineralnim pripravcima i sl., često nedovoljno učinkoviti. U ovom istraživanju praćena je učinkovitost novijeg pripravka fluralanera u jatu kokoši nesilica lake pasmine. Pripravak je primijenjen prema uputama proizvođača u dozi 0,5 mg po kilogramu putem vode za piće, dvokratno s razmakom od sedam dana. Praćena je invadiranost jata zamkama prije i nakon terapije, kao i nesivost kokoši. Rezultati pokazuju znatan pad broja tekuti u zamkama do devet dana nakon terapije te nestanak tekuti u objektu. Nesivost jata na farmi uspoređena je s prethodnim jatom, a rezultati pokazuju znatno višu nesivost u korist tretiranog jata. Potrebno je analizirati i hematološke parametre kako bi se utvrdio učinak pripravka na brzinu uspostave fiziološkog stanja organizma., 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.
