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

Anthelmintics, which remain the principal means for the prevention and control of subclinical and clinical ostertagiasis are reviewed under the headings: available anthelmintics (ivermectin, albendazole, fenbendazole, oxfendazole, thiabendazole, levamisole, morantel tartrate, phenothiazine,...

Abstract

Two studies were performed to investigate the efficacy of doramectin in the prevention of infection with Ostertagia ostertagi and Cooperia oncophora in grazing calves. In each study 24 parasite-naive calves were randomly allotted to 2 equal groups and treated with either doramectin at 200 µg/kg or...

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

Persistence of ivermectin anthelmintic activity in injectable and pour-on formulations against experimental infections of gastrointestinal nematodes in cattle was investigated in 5 groups of 6 calves each. Two groups were treated with the injectable or pour-on product at 14 days before experimental ...

Abstract

Gastrin values were evaluated in 130 parasite-free calves, in 61 first season grazing calves during 6 field trials and in 8 experimentally infected adult immune cows. The gastrin values were linked to pepsinogen levels and daily weight gain. Also the influence of thiabendazole treatment on...

Abstract

Three groups of 11 naturally infected crossbred beef calves were injected subcutaneously with moxidectin 1% injectable at 0.2 or 0.3 mg moxidectin/kg bodyweight or with the unmedicated vehicle. Nematode infections had been acquired during grazing from December to April. Based on the faecal egg...

Abstract

The susceptibility to morantel of a strain of O. ostertagi after 9 years of continuous use of morantel tartrate by Paratect bolus at a Friesian cattle farm in Viglunda, Sweden, was investigated. This was compared with a local strain of O. ostertagi from a nearby farm where no anthelmintics had been ...

Abstract

An experiment was conducted in calves to investigate the effect of sustained release (morantel, Paratect Flex) and pulse release (oxfendazole, Autoworm) anthelmintic intraruminal boli on the development of pathophysiological changes following daily infection with O. ostertagi and C. oncophora for 6 ...
