Gastrointestinal helminth infections of dairy goats in Slovakia

The aim of this study was to identify the most common gastrointestinal (GI) parasites in flocks of dairy goats on 30 farms in Slovakia. A total of 944 adult goats were examined during the pasturing seasons for 2014 – 2016. Eggs from one or more species of gastrointestinal parasites were identified in 906 of the samples (95.90 %). Strongyle eggs were present in most of the samples (92.00 %), followed by Strongyloides papillosus (14.05 %), Trichuris spp. (7.84 %), Nematodirus spp. (3.98 %), and Moniezia spp. (2.65 %). The counts of strongyle eggs per gram of faeces ranged from 0 to 11 000. Subsamples from each farm were used to prepare faecal coprocultures to identify the genera of the nematodes. Third-stage larvae of Trichostrongylus spp. (100 %) and Teladorsagia/Ostertagia spp. (96.60 %) were present on most of the farms, followed by Oesophagostomum spp./Chabertia ovina (86.60 %) and Haemonchus contortus (76.60 %). Teladorsagia/Ostertagia spp. were the dominant genera on 60 % of the farms.
