Abstract

The effect of an ivermectin sustained-release bolus (I-SRB) on the epidemiology of nematode parasites and on calf productivity was evaluated in a field trial under Northwestern European conditions. 20 parasite-naive female Friesian calves (principals) aged 5-9 months were used together with 6 male...

Abstract

The efficacy of two strategic treatments with doramectin (sc 200 µg/kg bodyweight) was studied in 20 first-season Holstein crossbred calves. The calves were allocated to two equal groups: Group D was treated with doramectin at turn-out and 8 weeks later and Group C served as control group. Tracers...

Abstract

A single treatment with doramectin (200 mg/kg s.c.) given at turnout was compared with a proven programme of 2 pour-on treatments with ivermectin (500 mg/kg) given at turnout and 6 weeks later in groups of 15 Holstein cross Friesian calves (10-12 months old). For a short grazing season of 126 days, ...

Abstract

This article poses, and discusses, the following questions: based on the distribution of cattle worldwide, what are the target parasites; can we continue to rely on control based mainly on the use of (highly effective) anthelmintics; what are the prospects for non-chemical control; who will develop ...

Abstract

A study was carried out to evaluate the effects of strategic early-season treatments with eprinomectin on first-season grazing calves exposed to strongyle infections on a naturally contaminated pasture. Two groups each of 10 first grazing season calves were turned out in mid-May 1997 on 2 plots in...

Abstract

In 1998 a questionnaire was sent to 2280 dairy cattle farmers in Flanders, Belgium, to investigate whether the pasture management included measures to control gastrointestinal nematodes, whether chemoprophylaxis was applied and whether chemoprophylaxis and grazing management were integrated, rather ...
