The behaviour pattern of several gastrointestinal nematode genera in sheep and cattle from bethausen, Timis County

Abstract

Parasitic infestations are one of the most important causes for animal disease and low productivity worldwide. Gastrointestinal nematodes (i.e. Trichostrongylus, ) as well as trematodes (i.e. Fasciola spp. Paramphistomum spp.), cestodes (i.e. Echinococcus spp.) and protozoa (i.e. Eimeria spp.) are all in the category of most important parasitic diseases. Studies were conducted on cattle and sheep from Bethausen village, Timis County. In cattle, the following genera were identified : Trichostrongylus, Cooperia and Ostertagia while in sheep the Trichostrongylus, Ostertagia, Chabertia, Oesophagostomum and Haemonchus genera were noticed. The present study was based on following the dynamics of the output of parasitic elements from the April 2015 until March 2016. The best represented genus was Trichostrongylus both in cattle and sheep with a prevalence of 40%, followed by Chabertia – 33%, Ostertagia – 30%, Haemonchus – 26% and Cooperia – 15%. The maximum EPG was achieved in October and the minimum EPG was achieved in the months of January and February.
