Abstract

Preliminary results of an experiment set up to elucidate whether mixed grazing can help controlling helminths in pigs and heifers are presented. No clinical symptoms were observed either in sows or in heifers. The mixed grazing had no detectable effect on the Oesophagostomum. dentatum infections of ...

Abstract

Recent advances in the knowledge of the life cycle and biology of Neospora are reviewed with the emphasis on bovine neosporosis. The role of the recently discovered oocyst stage of N. caninum in the epidemiology of neosporosis is discussed. Progress made in serological diagnosis of N. caninum...

Abstract

The occurrence of Toxocara vitulorum in cattle in Europe, Africa and Asia is briefly discussed. Susceptibility of different breeds, pathology, life-cycle, mode of infection and treatment are then considered in turn.

Abstract

Factors influencing the transmission of parasites via the application of slurry to pasture are discussed. Effects on grazing behaviour and grass intake are also briefly considered. Slurry application may also lead to parasite problems in farms where the animals are permanently housed. Control...

Abstract

Subcutaneous injection of 0.2 mg/kg ivermectin to heifers negatively affected larvae of D. quinquedens and O. gazella, developing in the dung. Although closely related, the 2 species seem to differ in susceptibility; 28% of brood masses made of dung voided 2 days after treatment contained 3rd...

Abstract

In a study on the effects of moxidectin for controlling trichostrongylosis in cattle in Inner Mongolia, piebald calves of the Friesian breed were allocated randomly to 3 groups on the basis of live weight. Group B was given moxidectin at turnout and at the beginning of 8th week; Group C was treated ...

Abstract

Six paddocks were established during the spring in Denmark on an old pasture grazed by yearling heifers the previous year. The paddocks were in pairs of equal size (1.10, 0.70 and 0.57 ha). One paddock of each size was grazed by 12 calves from mid-May to mid-July; the other paddocks were harvested. ...

Abstract

The epidemiology of H. placei and of other gastrointestinal nematodes in yearling dairy cattle was examined on two farms in Kiambu District, central Kenya during each of 13 one-month periods from April 1993 to April 1994. On each farm, 32 newly weaned dairy calves were given a single dose of...

Abstract

To examine whether susceptible calves grazing together with second-year resistant heifers are less exposed to trichostrongylid infection than are calves grazing on their own, 2 groups of animals representing each age category were turned out on to pasture on 24 May 1997 and grazed at comparable...
