Abstract

Dictyocaulus is the major strongyles causing respiratory disorders in small ruminants and is also considered a pathogen in the differential diagnosis of bovine bronchopneumonia. Diagnosis is easily confirmed through direct microscopic faecal examination of the affected animal. Treatment and disease ...

Abstract

In 2 field trials vaccination or different anthelmintic treatments against D. viviparus infections were used in 6 groups of first year grazing cattle. The antibody response to lungworm infections was determined using an ELISA. Cattle treated once or repeatedly at long intervals with levamisole...

Abstract

Two grazing experiments were performed to study the effect of moxidectin in a `dose and move' system on Dictyocaulus viviparus infections in calves. In the first experiment, 3 groups of 4 calves were experimentally infected with 20 larvae of D. viviparus 7 weeks before moxidectin treatment of 2 of...

Abstract

The danger that early season anthelmintic prophylaxis without vaccination may leave calves vulnerable to Dictyocaulus viviparus after midsummer is discussed. It is suggested that vaccination should be carried out before first grazing when the morantel device (Paratect Flex) is used but should be...

Abstract

A series of 28 controlled anthelmintic studies, involving 634 cattle, was conducted throughout North America and Europe to evaluate the efficacy of doramectin against a broad range of gastrointestinal parasitic nematode species and lungworms in naturally and experimentally infected animals. Within...

Abstract

Dictyocaulus viviparus were harvested from calves treated daily with albendazole at dose-rates sub-lethal to this parasite and from matched untreated calves. Male and female reproductive tracts from the worms were examined by light and transmission electron microscopy. A first description of the...

Abstract

A morantel tartrate bolus was administered to nine calves aged 4-5 months, before turning out in June. These and 9 untreated calves were subject to rotational grazing on 8 plots previously grazed by adult cattle. Faecal egg counts remained lower than those of the controls for 3 months. Some calves...

Abstract

The efficacy of moxidectin, a new endectocide against natural nematode infections, was evaluated. 25 calves were divided into 2 groups of 8 calves each and a 3rd group of 9 calves served as controls. Moxidectin was administered sc to 2 groups (I, 0.2 mg/kg bwt; II, 0.3 mg/kg bwt) and the 3rd group...

Abstract

Moxidectin, a macrocyclic lactone derived from Streptomyces cyanogriseus, was administered to 12 of 18 calves experimentally infected with D. viviparus as a s.c. injection at 0.2 mg/kg or a pour- on formulation applied to the skin of the back at 0.5 mg/kg. It was highly effective against the adult...

Abstract

Four groups of six parasite-naive calves were infected at seven day intervals with three doses of infective larvae of D. viviparus. Twenty-one days after the first dose three of the groups were treated either with an injectable formulation of ivermectin at a dose rate of 200 µg/kg bodyweight, or...
