flubendazole: safety regarding egg production and reproductive performance of breeder a comparative field trial, 5,950 meat breeder chickens were medicated via feed for 7 consecutive days with 60 ppm of the anthelmintic flubendazole. this treatment cured the birds of an infection with ascaridia galli and capillaria obsignata. a slight but transitory diarrhea was observed in treated chickens. the applied medication did not unfavorably affect egg production, fertility, or hatchability.19836847549
efficacy, pharmacokinetics and effects on egg-laying and hatchability of two dose rates of in-feed fenbendazole for the treatment of capillaria species infections in chickens.laying broiler breeder hens infected with capillaria obsignata were treated with in-feed fenbendazole either at a dose of 30 ppm for six days or 80 ppm for three days. the respective efficacies of treatment were 92.3 and 99.3 per cent. these results were a reflection of the plasma pharmacokinetics of fenbendazole and its metabolites in the regimens, which showed that the detectable plasma concentrations of the anthelmintically active fenbendazole sulphoxide in the second treatment were significa ...19938310628
pharmacokinetics and anthelmintic efficacy of febantel in the racing pigeon (columba livia).this paper reports on the pharmacokinetics and the efficacy of febantel against capillaria obsignata and ascaridia columbae in the racing pigeon. febantel was rapidly cleared from the circulation and highly metabolized. the efficacy of febantel against capillaria and ascaridia was studied on lightly and heavily infected pigeons. the efficacy against ascaridia was 100% for the faecal egg count reduction (fecr) as well as for the worm reduction in all treated pigeons. after two treatments with feb ...19938345572
