| Popis: | Ectoparasitic infestations with Linognathus stenopsis and Bovicola caprae are a serious concern in goat farms, especially during the winter and spring. This study tested the efficacy of three modern insecticide drugs (ivermectin, eprinomectin and amitraz) applied via different routes for control of sucking and chewing lice in naturally co-infected goats. Each of drugs was tested on 30 goats. The animals from the first flock were treated with a single dose of ivermectin, applied subcutaneously at 0.2 mg/kg, the second one received a single spot on treatment with 1 mg/kg еprinomectin and the third flock was treated twice with amitraz, through spraying at a dose of 4 mL/1 L water. The results were evaluated before the treatments and at post treatment days 3, 14 and 60. On post treatment day 60, the application of ivermectin resulted in reduction of Bovicola caprae population by 73.05%, and for that of Linognathus stenopsis: by 92.70%. Eprinomectin demonstrated 100% reduction of both lice. The reduction of L. stenopsis and B. caprae caused by amitraz was by 92.20% and by 98.61% respectively. The macrocyclic lactone eprinomectin showed the highest efficacy (Р |
