Abstract: A study was conducted in 1985 to determine gastrointestinal helminth prevalence, and intensity of infection. In dairy cattle on farms and pastures on the Avalon Peninsula, Newfoundland, using a fecal egg count technique. It was found that 55% of adult dairy cattle on ten farms in the St. John’s area were positive for helminth eggs. The mean egg count for the area was 1.2 eggs per gram of feces. The majority of the eggs (60%) were from a group containing the genera Ostertagia-Trichostrongylus-Cooperia, with 30% from Haemonchus-Oesophagostomum, 5% Bunostomum, and 5% trematodes. Trichuris eggs were noted in only one sample. Bovine fecal samples from community pastures showed a 39% prevalence with 50% of the eggs being from the Ostertagia-Trichostrongylus-Cooperia group. 22% Haemonchus-Oesophagostomum, 16% Bunostomum and 2% for each of Nematodirus, Trichuris and trematodes.
