Prevalence of Fasciola gigantica among sheep in Al-Anbar govrnorate and study of effect for aqoues extract of Urtica urens L. on Viability of Parasite.

Abstract

This study was conducted to investigate Prevalence of Fasciola gigantica in Al-Anbar govrnorate by test of (540) slaughtered sheep with different ages and sex (233 males and 307 females) in different areas in Al-Anbar govrnorate (Ramadi, Faluja, Heet, Hadytha, Rutba) by optical test for year 2012.The total infection was 8.3% The infestation percent in females was 10.4% which was higher than the infestation percent in males which was 5.5% .The infestation percent had increased with age progresses. The highest infestation percent was 14.2% at age more than eight years, Also, highest percentage of infection in Ramadi 11.3% and lowest percentage in Rutba 3.7%. Highest percentage of infecdtion was found in October 20% and November 13.6%which decline in June 3.2%.Significant differences were found between the number of Parasite in the gall bladder and their Liver for both males and females at (P> 0.05).The study included the inhibition effect of Urtica urens aqoues extract on Fasciola gigantica viability, the results indicated that F. gigantica viability decreased by (0.1) to (10) Mg/ml concentration and more decreasing by more concentrations, that the viability rate decreased.
