Abstract
The objective of this study was to evaluate the species composition of protozoan and helminth parasites of young calves on farms in eastern Slovakia. Faecal samples from calves were analysed using the floatation technique, McMaster Methods and stained slide method for Cryptosporidium spp. From 105 samples analysed, nine samples (8.6 %) were suspected to be positive for Cryptosporidium spp. The results gathered from this study displayed that 64.8 % of calves were infected with some species of parasite at the moment of sampling. The highest prevalence of infection was with Eimeria spp. with 56.2 % of calves infected being positive for this. OPG (oocysts per gram) values for Eimeria spp. observed in this study ranged from 100 to 75,200. The lowest prevalence was found to be from Giardia duodenalis and Trichostrongylidae family equally 0.95 %. All faecal samples had nematode egg counts below 50 EPG (eggs per gram).
