Abstract

Condensed tannins' (CTs) fate along the digestive tract of ruminants may account for the variable efficacy of CTs against gastrointestinal nematodes. We analyzed CTs in the digesta of cattle fed sainfoin. With the acetone-butanol-HCl assay, the total CTs concentrations in the digesta were close to...

Abstract

Background: Gastrointestinal nematodes (GINs) can cause significant economic losses in alpacas due to lowered production of fibre and meat. Although no anthelmintics are registered for use in alpacas, various classes of anthelmintics are frequently used to control parasitic gastroenteritis in...

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

Sainfoin (Onobrychis viciifolia) is a condensed tannin (CT)-containing legume and has anthelmintic potential against gastrointestinal nematodes of ruminants. This study investigated in vitro effects of acetone/water extracts and derived CT fractions from different types of sainfoin (i.e....

Abstract

The use of natural plant anthelmintics was suggested as a possible alternative control of gastrointestinal nematodes (GIN) in ruminants. Direct anthelmintic effects of tannin-containing plants have already been shown in sheep and goat GIN. These anthelmintic properties are mainly associated with...

Abstract

Resistance to anthelmintics is an increasing problem in sheep, goat and cattle industries worldwide. For parasite management on farms reliable methods for the detection of resistance are required and it is important that tests give comparable, reproducible and reliable results in different...

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

The influence of prophylaxis on the immune response to gastrointestinal nematodes was evaluated in 3 groups of 10 first-season grazing calves. Group C functioned as untreated controls, whereas Group L received 2 treatments, one at turn-out and one 8 weeks later, with doramectin (200 µg/kg) and...

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...
