Abstract

Abomasa, blood samples and faecal samples for examination of nematode infections were collected from 125 dairy cows between November 1997 and October 1998. Of these, 12 had no grazing history and were therefore excluded from the study. Of the remaining 113, 88.5% had nematode eggs in their faeces....

Abstract

Three trials using 50 European breed cattle were conducted to evaluate the therapeutic and prophylactic efficacy of a sustained-release bolus designed to release 12 mg of ivermectin per day for 135 days (the Ivomec SR Bolus) against nematodes (2 trials) and P. ovis (1 trial) in 16- to 19-month-old ...

Abstract

Hereford-Friesian heifers, 4 months of age, weighing 88-130 kg were given a placebo bolus (controls) or a prototype intraruminal sustained-release bolus designed to deliver approximately 8 mg ivermectin/day for 100 to 120 days. The boluses were administered the day before turnout in mid-May. Each...

Abstract

The therapeutic efficacy of doramectin administered subcutaneously at a dose rate of 200 µg/kg (1 ml/50 kg) was assessed in cattle harbouring natural mixed field infections of gastrointestinal and pulmonary nematodes in Minas Gerais, Brazil. Twenty male 10- to 15-month-old Zebu × Holstein calves...

Abstract

Efficacy of abamectin against gastrointestinal tract nematodes and lungworms of cattle was determined in 4 experiments.

Abstract

Tests on a limited scale of the anthelmintic efficiency of tetramisole are reported. By means of total tracheotomy and the recovery of worms from bronchial mucus of calves experimentally infected with Dictyocaulus viviparus it was shown that the drug given at the rate of 10 mg/kg led to the...
