Abstract

A vaccine containing integral membrane glycoproteins from the intestine of Haemonchus contortus was evaluated in four groups of nine worm-free calves challenged with either 8000 H. contortus or Haemonchus placei infective larvae. Vaccinates received 50 µg of the antigen and 1 mg QuilA adjuvant...

Abstract

The bovine lungworm Dictyocaulus viviparus is of major economic importance in cattle farming in the temperate zones. The invertebrate protein paramyosin is one of the main components of muscle thick filaments but can also exhibit immunomodulatory functions. It represents a promising vaccine...

Abstract

Twenty-four Holando Argentino male calves were treated orally with 50 mg/kg body weight trichlorphon (TCF); 0.2 mg/kg body weight subcutaneous ivermectin (IVM); a combination of TCF+IVM at the same doses and administration routes; or remained untreated (control group). All calves were necropsied at ...

Abstract

Biological control is an alternative method to reduce parasite populations by the use of a natural antagonist. In the present study, efficacy of the nematophagous fungus Duddingtonia flagrans was tested to control gastrointestinal nematode parasites of cattle in the field. Twenty calves were used,...

Abstract

The anthelmintic resistance of bovine nematodes against ivermectin was determined in 2 farms in southern Chile. A total of 14 and 22 bovines aged 7-8 months from farms 1 (near Purranque) and 2 (near San Pablo), respectively, were treated with 0.2-ml/kg ivermectin. Faecal samples were obtained from...

Abstract

Cooperia oncophora is an important parasitic nematode of cattle with a wide distribution in temperate areas. Twenty Holstein nematode-naïve bull calves were experimentally infected with approximately 100,000 infective L3s and infection was allowed to progress for 7, 14, 28, 42 days, respectively....

Abstract

The interaction between parasitism and crude protein (CP) nutrition on calf liveweight gain (LWG) was investigated. One hundred and twelve calves were either administered 21,000 parasite larvae (73% Cooperia oncophora, 16% Ostertagia ostertagi, 11% Trichostrongylus axei) twice per week or drenched...

Abstract

The pattern of longitudinal ridges (synlophe) on the external cuticular surface of trichostrongylid nematodes has been shown to be of value for distinguishing species and determining relationships among higher taxa. In the process of studying Mecistocirrus digitatus, the large stomach worm of...

Abstract

In two trials 5 calves were each experimentally infected on 3 consecutive days with a total number of either 30 D. viviparus larvae per kg body weight (trial A) or 3 larvae/kg body weight (trial B). Five calves served as non-infected controls. Infected cattle in trial A developed severe clinical...

Abstract

The effect of annually alternating cattle and sheep was investigated in UK as an alternative to drug therapy in the control of bovine helminth infections. Until the second grazing season this system appeared to be successful, with a marked reduction in cattle worm burdens. However, by the end of...
