The scientific paper elucidates the importance of using remedies of natural origin, compared to those of chemical origin, in combating ectoparasites in gallinaceous birds. For the first time, the antiectoparasitic efficacy of the natural extract Ectogalimol, obtained from the plant raw material, dry aerial parts of the Dalmatian chamomile (Pyretrum cinerariifolium Trev.) which in a concentration of 3%, administered by spraying in two rounds at an interval of 14 days, in a dose of 50 ml per bird, possesses a high therapeutic effectiveness against the various species of ectoparasites (bird lice, fleas and gamasid mites). For comparative purposes, the drug Ivermec-OR is used, which also possesses a high antiparasitic efficacy against various species of bird lice, fleas and gamasid mites in gallinaceous birds, compared to the natural extract Ectogalimol, which does not require restrictions on the consumption of products and by-products from treated birds.
