In this work, ١٥ digestive systems of Syrian Awass sheep, slaughtered in
Hama abattoir were examined, in addition faeces smaers, livers, lungs and

Very high infestation percent of Gastro-intestinal helminths was evident
.
Generally the intensity of infestation was of medium range, but it was very
high in the abomasum, then the small intestine and the large intestine in
decreasing order.
٢٣ species of Nematodes were identified, in addition to ٤ species of
Cestodes, Dicrocoelium dentriticum, ٢ larval-stage (Cysticercus tenuicollis and
