Abstract
Four hundred livers and four hundred lungs comprising two hundred each from sheep and goats were examined for the presence of belminthic infections. The results showed that overall incidence of parasitic infection in livers was 34% in sheep and 11% in goats. In lungs, the parasitic infection was recorded as 21% in sheep and 8% in goats, flydatidosis observed in sheep and goats 24 was. 24 and 8%, respectively. Fascioliasis in sheep and goats was recorded as 18 and 10 respectively involving two species viz. Faso gigaafica and Faso' °la hepatica. Among lungworms, Dietyacaulta filaria was recorded from 3% and Prorostrongylits mfe.Pcens from 2% lungs of sheep only. Taxocara cams larvae were found in 4% sheep and I yo goat livers.
INTRODUCTION
Parasitism affects all classes of livestock throughout the world. h has been established that worm infestation is one of the major constraints is the development of profitable livestock industry. In severe outbreaks,helminths cause serious economic losses due to mortality. However, in even apparently healthy animals insidous nature of parasite resuItes in reduced productive efficiency. This is the reason that in.spite of large numbers of sheep and goats, they arc unable to meet the demands of the fast growing human population. Among various parasitic diseases of sheep and goats those affecting vital body organs like liver and lungs cause enormous damage. Livers and lungs being vital organs play crucial role in productive efficiency of the animals and have therefore been examined for parasites in the present study.
MATERIALS AND MrriTODS
Four hundred livers and four hundred lungs comprising two hundred each from sheep and goats were collected from Faisalabad abattoir. Livers and lungs were incised through biliary tree and trachca, bronchi, bronchioles respcc-
