Efficacy of dichlorvos, fenbendazole, and ivermectin in swine with induced intestinal nematode infections.
Am J Vet Res. 1987 Aug; 48(8):1233-5.AJ

Abstract

Anthelmintic efficacies of dichlorvos, fenbendazole, and ivermectin were compared in specific-pathogen-free crossbred weanling pigs inoculated with Ascaris suum, Trichuris suis, and Oesophagostomum dentatum. On postinoculation day (PID) 50, 24 pigs in each treatment group were treated orally with 43 mg of dichlorvos/kg of body weight, 3 X 3 mg of fenbendazole/kg, or 300 micrograms of ivermectin/kg, SC. Twenty-four pigs were not treated. On posttreatment day 7 (PID 57), 12 pigs from each treatment group (phase I) were slaughtered, and the anthelmintic efficacy of each treatment was determined. Efficacies against A suum, T suis, and O dentatum, respectively, were: dichlorvos, 100%, 99.9%, and 100%; fenbendazole, 100%, 99.8%, and 100%; and ivermectin, 98.7%, 53.9%, and 87.6%. Weight gains and feed conversions of the remaining pigs were monitored until they reached market weight (phase II). The average weight gains (kg) and feed conversions (kg of feed/kg of gain) at posttreatment day 81 (PID 131), respectively, were: 73.6 and 3.44 for nontreated controls, 78.9 and 3.31 for dichlorvos-treated pigs, 72.1 and 3.36 for fenbendazole-treated pigs, and 74 and 3.48 for ivermectin-treated pigs. Differences in average weight gains and feed conversions were not significant (P greater than 0.05).
