Animals with low eggs per gram of feces (epg) values before pasturing also had lower values at the end of the grazing season and sheep with higher values had higher values at the end of the grazing season.

Haemonchus (H.) contortus was the second most frequent nematode both before and after grazing with 18.4% and 31.2%, respectively, and more commonly found than in previous studies from Austria. The proportions of Trichostrongylus (p = 0.00\ufeff) and Nematodirus (p = 0.032) decreased and H. contortus (p = 0.005) increased significantly between the two different sampling dates.

Das Ziel dieser Studie war es, die Pr\u00e4valenz von ovinen gastrointestinalen Strongyliden (GIS) zu bestimmen und den Einfluss der Alpung auf die Verbreitung der GIS-Infektion w\u00e4hrend der Weidesaison in \u00d6sterreich zu ermitteln. Die Untersuchung umfasst 2\ufeff3 adulte Schafe von 16 verschiedenen Betrieben, die gemeinsam gealpt wurden. Einzelkotproben wurden zu verschiedenen Zeitpunkten gewonnen. Vor der Entwurmung und nach der Alpung wurden Kotproben qualitativ (Flotation und Kotkultur) und quantitativ (f\u00e4kale Eizahlbestimmung) untersucht. Zus\u00e4tzlich wurden w\u00e4hrend der Alpung Kotproben zweimal quantitativ (f\u00e4kale Eizahlbestimmung) analysiert. Vor der Entwurmung und der Alpung lag die Pr\u00e4valenz von GIS bei den untersuchten Schafen bei 4\ufeff,7 %, nach der Alpung bei 100%, dieser Anstieg war signifikant (p lt; 0,001). Zus\u00e4tzlich konnte ein signifikanter Anstieg (p lt; 0,001) bei der Eiausscheidung w\u00e4hrend der Alpung nachgewiesen werden. Tiere, die vor der Alpung einen niedrigen \u201eeggs per gram of feces\u201d (epg-Wert) aufwiesen, zeigten tendenziell auch niedrigere Werte am Ende der Weidesaison, und Tiere mit h\u00f6heren epg-Werten hatten auch h\u00f6here Werte am Ende der Weide saison. Trichostrongylus war sowohl vor (\ufeff5,6 %) als auch nach der Alpung (38,8 %) der dominanteste GIS in der Kotkultur. Haemonchus contortus war der zweith\u00e4ufigste Nematode vor und nach dem Weidegang mit 18,4 % und 31,2 % und wurde in dieser Arbeit deutlich h\u00e4ufiger nachgewiesen als in vorangegangenen Studien. Das Vorkommen von Trichostrongylus (p = 0,00\ufeff) und Nematodirus (p = 0,032) sank und H. contortus (p = 0,005) stieg signifikant zwischen den beiden Beprobungszeitpunkten.
