Abstract

A study of seasonal trends of gastrointestinal nematode infection and disease of cattle in relation to climate and management conditions suggested a need for strategic deworming treatments to reduce exposure. A primary programme of 3 treatments at long intervals succeeded in 4 yearly experiments....

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

An experiment was conducted to compare the anthelmintic efficacy of albendazole (ABZ), levamisole (LEV) and fenbendazole (FBZ) against inhibited early 4th-stage larvae (EL4) of Ostertagia ostertagi during April in Louisiana, USA. Forty cross-bred beef heifers (average weight 165 kg) were acquired...

Abstract

The anthelmintic efficacy of abamectin (avermectin B) was evaluated against gastrointestinal nematodes, including O. ostertagi inhibited larvae and lungworm, in yearling crossbred beef heifers in Louisiana, USA, during late spring. The calves were grazed on contaminated pasture for 10 weeks and...

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....

Abstract

The efficacy, safety, and compatibility of fenbendazole (FBZ) and clorsulon (CLN) were tested after oral administration of label recommended and of higher (5×) dosage rates to calves naturally infected with gastrointestinal nematodes (Ostertagia ostertagi, Trichostrongylus axei, Haemonchus sp, ...

Abstract

Levamisole (LEV) was tested in 4 experiments to compare efficacy values against O. ostertagi when larval maturation was occurring (September), following inhibition and also when populations were expected to be largely adult (winter). A primary objective was to determine the importance of developing ...

Abstract

In Louisiana, USA, 2 yearling cattle were removed from pasture in late January, 2 in early February and 3 in early March. All were held in drylot for 2 or 3 weeks before slaughter. Ostertagia ostertagi worm burdens of those removed in January and February were similar but in the February group the...

Abstract

In Louisiana, USA, calves naturally infected with Fasciola hepatica were treated in groups of 7 or 8 with albendazole as a 4.55% (w/v) drench suspension. Comparison with the fluke burdens of untreated controls after 21 to 24 days showed that a dose of 7.5 mg/kg was 77.5% effective against mature...

Abstract

The efficacy of febantel at a dosage of 5 mg/kg (45.5% paste formulation) against inhibited early 4th-stage larvae (EL4) of Ostertagia ostertagi, other nematodes of the abomasum, and Dictyocaulus viviparus was investigated in 4- to 6-month-old Holstein calves that grazed on pasture heavily...
