Farms 1, 2, 3, 4, 7 and 9 were located on the sides of hills in rolling terrain and were welldrained. Farm 5 had a similar topography but the pastures contained wet spots. Flat, wet pastures were a feature of farm 6, while farms 8 and 10 had rolling to flat pastures with wet areas, and considerable marshland on the latter farm. Fecal samples were obtained from the dairy cattle on a regular monthly basis with samples being taken during the morning milking from each of ten different animals In each herd. When an animal evacuated a sample was taken from the top of the freshly dropped feces, placed in a styrofoam cup and taken back to the laboratory for processing that day using a formalin-ether sedimentation technique (6). Eggs detected in the sediment were placed In one of six groups based on shape, size and cell numbers present (4, 5) and the number of eggs per gram of feces (epg) calculated. The groups were a) OstertagiaTrichostrongylus - Cooperia

; b) Haemonchus - Oesophago^tomum

;; c) Bunostomum

; d) Nematodirus; e) Trlchuris; and f) flukes (including Paramphistomum, Fasclola and DIcrocoellum

)

. The second part of this project was carried out in the summer of 1985 an four community pastures on the Avalon Peninsula (Fig. 1). Pastures in Brigus and Gaskiers were each visited twice, once on June 28 and again on August 8, while Shoe Cove was visited on June 25, July 30 and August 27, and Aquaforte on July 4, July 25 and September 3. The number of Fig. 1: Locations of sample sites: 1-10 correspond to farms discussed in the text, 11-14 to community pastures (11 = Aquaforte, 12=Gaskiers, 13= Brigus, 14=Shoe Cove)
