Abstract

The persistent activity of ivermectin long-acting injection (IVM LAI; IVOMEC® GOLD, Merial; 3.15% ivermectin w/v) against nematode infections of cattle was evaluated under natural challenge conditions. Seventy nematode-free Brown Swiss calves were blocked by pre-treatment bodyweight and allocated...

Abstract

Nematode parasitism of feedlot cattle has received very little research attention. It is assumed that anthelmintics administered at feedlot entry are effective and that feedlot conditions preclude post-treatment infection by helminths. Given the paucity of information about feedlot nematodiasis,...

Abstract

Next-generation deep amplicon sequencing, or metabarcoding, has revolutionized the study of microbial communities in humans, animals and the environment. However, such approaches have yet to be applied to parasitic helminth communities. We recently described the first example of such a method -...

Abstract

A two-year study was conducted to assess the effects of ivermectin (with clorsulon) and long-acting moxidectin on the development of replacement beef heifers carrying naturally occurring parasite infections. Replacement beef heifers (n=105) were obtained at weaning and co-grazed on permanent...

Abstract

With the aim to evaluate the effect of ivermectin 2.25%+abamectin 1.25% in the reduction of gastrointestinal nematodes eggs per gram (epg) and the weight gain in bovines in 90 days, twenty four Santa Gertrudis breed, weaned calves localized in a ranch in Malpaso, Tecpatan municipality, Chiapas,...

Abstract

This study was conducted to assess effectiveness, safety and benefit of injectable moxidectin compared to an injectable ivermectin-clorsulon combination. A total 2,022 stocker calves maintained on 11 Arkansas and Missouri cattle farms were randomly and evenly allocated on each farm into either the...

Abstract

The present investigation was made with the purpose of determining the anthelmintic resistance of nematodes to fenbendazole 10%, albendazole 10%, levamisole 15% and ivermectin 1%. On each farm, 50 cattle positive for gastrointestinal nematodes were used. The therapeutic dose of fenbendazole and...
