Comparison of gut parasites incidence on chosen farms
HUBENÁ, Lucie
The main goal of the thesis was to compare prevalence of intestinal parasites of cattle in farms using different technologies of breeding, and evaluation of the obtained data. Irregularly, from spring to autumn 2010, faeces samples of dairy and meat cattle were collected from the chosen farms. A total of 425 samples of cows from three farms was collected. Two of the three breeds (herd A and B) consisted of Holstein and Fleckvieh Breed, first of the herds was pastured. The third herd (C) was of Limousine breed and was pastured whole season. The samples were collected in plastic containers in fresh state. In the examined samples, gut parasites of genus Eimeria and helminthes of the family Trichostrongylidae were diagnosed. In the herd A, no intestinal parasites were found. The most common parasites diagnosed in the herd B were coccidia (38%). Helminths of family Trichostrongylidae were also diagnosed (16,6%). In the herd C, both coccidia of the genus Eimeria and parasitic helminths were found (thirs prevalence was 38% and 26%, respectively). Seasonal dynamics of the parasites was also monitored, a descending trend was detected from summer to autumn. Prevalence in the herd B was 64% in summer, 58% in autumn, in the herd C were the respective prevalences 66% and 70%.
