Abstract

Background: Gastrointestinal nematodes (GINs) can cause significant economic losses in alpacas due to lowered production of fibre and meat. Although no anthelmintics are registered for use in alpacas, various classes of anthelmintics are frequently used to control parasitic gastroenteritis in...

Abstract

The objective of this study was to evaluate the status of anthelmintic resistance (AR) in ruminants and horses in Spain. The efficacy of commonly used macrocyclic lactones (MLs) - ivermectin (IVM) and moxidectin (MOX) - was measured in sheep, cattle and horses. In addition, albendazole (ABZ) and...

Abstract

A total of 324 steers were randomly allotted into 4 treatment groups. Preliminary slaughters indicated that 95% of the cattle had O. ostertagi inhibited larvae. Nine calves from each group were examined at slaughter for efficacy evaluation 12 or 13 days after treatment. Efficacies against inhibited ...

Abstract

In five trials conducted in different regions of France during 1988, 15-21 calves given the morantel tartrate bolus were introduced to contaminated pasture plots as were similar numbers of control calves and, in two trials, similar numbers of calves given a levamisole bolus. Monthly faecal egg...

Abstract

Two experiments with a morantel resistant strain of O. ostertagi were carried out. In the first experiment, 5 groups of 5 calves were infected with 60 000 larvae of this resistant strain. Calves of one group remained untreated, calves of the other groups were treated with morantel tartrate,...

Abstract

In field trials in 1983-84, Hereford weaner steers were given no anthelmintic treatment or were treated with morantel slow release bolus, pour-on levamisole or albendazole orally. Nematode egg counts in faeces were generally <50/g, indicating low numbers of adult nematodes. Treatment significantly affected mean faecal egg count, those for controls and morantel being 16 and 10/g above the overall mean (47/g) and levamisole and albendazole 6 and 12/g below the mean. There were no significant differences between treatments in numbers of larvae on pasture. At the end of both years most nematodes were early 4th stage larvae of O. ostertagi. There were no significant differences in nematode counts or...

Abstract

Following treatment of a group of 6 animals with levamisole (5 mg/kg im) on a beef cattle farm in Flanders, Belgium, the reduction in trichostrongylid faecal egg output varied between 0 and 66.6%, whereas a similar group treated with fenbendazole (7.5 mg/kg per os) showed a 100% reduction....

Abstract

176 newly received steer and bull calves and yearlings, average body weight 506 lb, were injected with ivermectin (91 µg/lb), fenbendazole (2.3 mg/lb) or levamisole phosphate (2 mg/100 lb) for control of Ostertagia ostertagi, or left untreated as controls. Daily gains (lb/head) of cattle in the...

Abstract

The effect of a slow release intraruminal bolus containing 22.2 g levamisole was tested in 5 Friesian type calves reared indoors until 12 weeks old. 5 similar calves were used as controls. All 10 calves were infected twice weekly for 6 weeks with 2500 Ostertagia ostertagi and 2500 Cooperia...

Abstract

An experiment was conducted to compare the anthelmintic efficacy of albendazole (ABZ), levamisole (LEV) and fenbendazole (FBZ) against inhibited early 4th-stage larvae (EL4) of Ostertagia ostertagi during April in Louisiana, USA. Forty cross-bred beef heifers (average weight 165 kg) were acquired...
