Abstract

The objective of this study was to evaluate the status of anthelmintic resistance (AR) in ruminants and horses in Spain. The efficacy of commonly used macrocyclic lactones (MLs) - ivermectin (IVM) and moxidectin (MOX) - was measured in sheep, cattle and horses. In addition, albendazole (ABZ) and...

Abstract

The efficacy of 0.5% moxidectin pour-on at 2 dosages was evaluated in 30 cattle with naturally acquired gastrointestinal nematode infections. The cattle were ranked according to pretreatment faecal egg counts and body weights, and were randomly assigned from replicates to 3 treatment groups. The...

Abstract

Efficacy of a spring strategic treatment programme with fenbendazole (FBZ) to reduce the accumulation of Ostertagia ostertagi inhibited early fourth-stage larvae (EL4) was investigated in two groups of crossbred beef heifers in Louisiana, USA, which were 7-9 months of age and ranged in weight from...

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

The epidemiology and the effect on live weight gain (LWG) of internal parasites was studied on weaned heifers from May to December during 1990 and 1991. In each period 2 groups of 20 calves were chosen at random and grazed the same natural pasture. The stocking rates were 1 head/3.5 ha (1990) and 1 ...

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

In vivo measurements of total body water, exchangeable sodium and exchangeable potassium, were made by radioisotopic dilution techniques, in 20 calves exposed to natural infections with Ostertagia ostertagi, Cooperia oncophora, and Nematodirus battus during their first grazing season. Ten calves...

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 anthelmintic efficacy of ivermectin (IVM) delivered from a sustained-release (SR) bolus was evaluated against natural infections with gastrointestinal tract nematodes in 12 crossbred beef heifers in spring in Louisiana, USA. The 12 calves were randomly allotted to 2 groups of 6 calves each....
