Abstract

This article is the first of a two-part series discussing the worming regimes of gastrointestinal (GI) parasites in relation to immunity and pasture rotation. The anthelmintics used to control these parasites are examined. Moreover, the lungworm Dictyocaulus viviparus which is directly affected by...

Abstract

Eprinomectin has been approved for use as a topically applied endectocide for beef and dairy cattle. To determine if eprinomectin has utility as an injectable anthelmintic, it was titrated at 0.05, 0.1, and 0.2 mg/kg s.c. against adult (Trial 1) and at 0.05, 0.1, 0.14, and 0.2 mg/kg s.c. against...

Abstract

Two studies were conducted, one in Quebec, Canada and one in Idaho, USA, to determine the persistent efficacy of doramectin pour-on against an artificial, trickle challenge of mixed nematodes in calves. In each study 42 Holstein calves, 4-8 months old and kept indoors, were randomly assigned to 4...

Abstract

Two studies were conducted with doramectin topically administered at 500 µg/kg body weight to assess retention of therapeutic efficacy against nematode infections of cattle before, and after, simulated rainfall. In the first study, 50 heifers, with patent nematode infections, were allocated to 5...

Abstract

The persistent activity of moxidectin topically administered at the dose rate of 0.5 mg/kg bwt was evaluated against experimental nematode infection in 30 calves randomly allocated to 6 groups. Five groups were treated on days -42, -35, -28, -21 and -14. The 6th group remained untreated as a...
