Abstract :
The aim of present study was determination of alimentary helminthic parasites of sheep Sanandaj. 100 alimentary tract (from oesophagus to rectum) were examined. Oesophagus was examined with direct observation. Other parts of digestive canal were examined by washing their contents separately. The worms found in the washed contents of alimentary were collected, counted and identified microscopically after being cleaved in Lactophenol. Oesophagus, Abomasum, small and large intestine were infected with 9 species of nematodes and 2 species of cestode. The rate of helminthic infection in sheep were 38% . The number of nematodes recovered from the gastro-intestinal ranged from 1 to 650 per host. Helminthic infection was not seen in Rumen or reticulum. The results of helminthic infection relating to other parts of alimentary tract were seen as follows. Oesophagus: Gongilonema pulchrum(5%), Abomasum: Haemonchus contortus(1%), Marshallagia marshalli(5%), Ostertagia occidentalis(11%), O.circumcincta(2%), Small intestine: Nematodirus oiratianus(8%), Moniezia benedeni(3%) and Avitellina centripunctata(12%), Large intestine: Oesophagostomum venulosum(2%), Trichuris ovis(10%) and Skrjabinema ovis(3%). Results shows the high contamination of gastrointestinal under animals is the parasitic worms.
