Summary

An investigation into the helminth species present in cattle in the East Kimberley and Victoria River Districts of Northern Australia was conducted over a 2-year period based on bi-monthly total and differential worm counts in weaner cattle as well as on apost mortem survey of adult cattle sent for slaughter.

The most important species found in young cattle wereHaemonchus placei andCooperia spp. Only small numbers ofBunostomum phlebotomum, Nematodirus spathiger, Oesophagostomum radiatum andMoniezia benedini were present.Calicophoron calicophorum and nodules ofOnchocerca spp. andOe. radiatum were recorded in adult cattle. Seasonal fluctuations in helminth parasite burdens are discussed in relation to temperature and rainfall and the results are interpreted in relation to the effects of helminthosis on present and future beef production in this area.

Helminthes Du Bétail Du Boucherie Dans Les Districts D'east Kimberley Et De Victoria River, Dans L'australie Du Nord

Résumé

Une enquête sur les différentes espèces d'helminthes hébergées par le bétail dans les districts d'East Kimberley et de Victoria River, a été conduite pendant deux années sur la base du décompte une fois tous les deux mois total et différentiel des vers trouvés tant sur du bétail sevré que chez des animaux adultes autopsiés à cet effet aux abattoirs.

Les espèces les plus importantes trouvées chez les jeunes animaux ont étéHaemonchus placei etCooperia spp. alors queBunostomum phlebotomum, Nematodirus spathiger, Oesophagostomum radiatum etMoniezia benedini n'ont été trouvé qu'en faible nombre.Calicophoron calicophorum et des nodules d'Onchocerca spp. etO. radiatum ont été trouvés chez le bétail adulte.

Les fluctuations saisonnières de ces helminthes parasites sont discutées en relation avec la température et la pluviosité et les résultats interpretés en relation avec les répercussions que peuvent avoir ces verminoses sur le présent et l'avenir de la production de viande dans cette région.

Parásitos Helmintos En El Ganado De Carne De Kimberley Oriental Y Rio Victoria, Distritos Del Nordeste De Australia

Resumen

Se realizó una investigación parasitológica sobre las especies de helmintos prevalentes en el ganado de carne de los Distritos de Kimberley Oriental y Río Victoria en el nordeste de Australia. El estudio tuvo una duración de dos años ye se basó en conteos bimensuales totales y diferenciales de parásitos en animales jóvenes, y adultos enviados al matadero.

Las especies más importantes encontradas en animales jóvenes fueronHaemonchus placei yCooperia spp. De menor importancia fueronBunostomun phlebotomum, Nematodirus spathiger, Oesophagostomum radiatum yMoniezia benedini. En ganado adulto se encontróCalicophoron calicophorum y nodulos deOnchocerca spp. yOesophagostomum radiatum. Se discuten las fluctuaciones estacionales parasitarias con relación a la temperatura y el régimen de lluvias, asi como la interpretación de los resultados con relación a los efectos de la helmintiasis en el presente y futuro de la producción de carne en el área.
