Use of eprinomectin (Eprinex Pour-On) to control natural infection by gastro-intestinal nematodes in goats

The aim of this study was to evaluate Eprinex Pour-On against gastro-intest inal nematodes in naturally infected goats. Two groups, each including adul ts and one-year old goats were treated with standard bovine dose and double dose rate. The prevalence and intensity of gastro-intestinal nematodes inf ection was determined based on faecal samples examination on the day of tre atment (day 0) and 7, 14, 34, 56, 90 and 125 days after the treatment. The low efficacy of the recommended bovine dose rate was stated within the firs t two weeks after the treatment (59.5% and 89.9% in adults and yearlings, r espectively). in double dosed animals, the efficacy was 97.6% and 88.5% on the 56th day after dosing in adults and young, respectively. The results of the study demonstrate the high and persistent efficacy of Eprinex: against gastro-intestinal nematodes in goats in a double bovine dose rate. They al so indicate the dose is highly effective against the mucosal stages of goat s) nematodes.
