Abstract

The effect of climatic factors on the development and migration of C. oncophora and O. ostertagi L3 in cattle faeces placed on pasture between June and the end of September, and on the dynamics of contamination of pasture grazed by calves was studied in 1987 in Baunschweig-Völkenrode, northern...

Abstract

A grazing experiment was performed in the Swiss midland region with 22 first-season calves which were grazed together from May to mid July when they were allocated to 2 equal groups, one receiving a morantel sustained-release trilaminate bolus (Paratect Flex) and the other one remaining as an...

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...

In the alpine region, mixed grazing systems with cattle of different age, origin and prophylaxis against trichostrongylid infections are most common. Under these conditions the administration of anthelmintic devices to susceptible calves is frequently postponed to June or July to achieve a better...

Abstract

In organic farming grazing is essential for ruminants, while for pigs and fowl an outdoor-run has to be available. This provokes a higher infection risk for endoparasites. Endoparasite control has to consider the restrictions of the rules for organic production. Preventive treatment with...
