Abstract

The duration of the anthelmintic activity of abamectin administered by sc injection at 200 µg/kg was determined using induced infections of Haemonchus placei, Ostertagia ostertagi, Cooperia spp., and Oesophagostomum radiatum in cattle. 24 Friesian calves, raised under worm-free conditions, were...

Abstract

Two studies demonstrated the persistent activity of ivermectin injected subcutaneously into cattle at 200 µg/kg in preventing the establishment of induced infections with Ostertagia ostertagi, Cooperia oncophora and Dictyocaulus viviparus. There were reductions in mean worm count (compared with the ...

Abstract

Three worm-free calves aged 6 to 7 months were injected subcutaneously with ivermectin at 200 µg/kg and 7 days later they were infected orally with a mixture of infective larvae (5000 Haemonchus placei, 20 000 Cooperia pectinata, 3000 Oesophagostomum radiatum). Larvae from the same source were also ...

Abstract

Two formulations of avermectin B1a, C-076 and MK-933, were examined for anthelmintic activity in two trials, each using 20 calves with experimental nematode infections. In one trial, C-076 was given orally, and in the other trial, MK-933 was given by injection at dosages of 50, 100, and 200 mu...

Anthelmintic activities of fenbendazole were evaluated in a controlled experiment. Forty calves artificially infected with gastrointestinal nematodes were allotted to 4 groups. Calves in group 1 were used as nonmedicated controls; the other calves were given (orally) fenbendazole at the dose level...

Abstract

Oxfendazole given to calves at 2.5 mg/kg as a paste, a bolus, or a drench resulted in excellent (97-100%) anthelmintic efficacy against mature Ostertagia ostertagi, Trichostrongylus axei, Cooperia oncophora, C. mcmasteri, C. pectinata, C. punctata, Nematodirus helvetianus, Trichostrongylus...

Abstract

A controlled test of the activity of three formulations of levamisole, at the dose level of approximately 8 mg/kg, against naturally occurring infections of gastrointestinal parasites and lungworms was made in 24 calves (6-21 months old) allotted to four groups of six calves each. Levamisole was...
