Abstract
This experiment was conducted on to study how some production traits selection which carried on as (weight gain and staple length) be affected and to detect the innate or acquired resistance and susceptibility of Awassi local breed of sheep against Fascioliasis of F.gigantica and the mix infection with Haemonchosis of H.contortus. A nine sheep of Awassi local sheep breed, was divided in to two treatment groups as the followings: Control group contain 4 heads and treated group 5 sheep to be experimentally infected with 3metacercaria/kg B.W. of F.gigantica and 500 L3 /kg B.W. of H.contortus. The experiment lasted 20 week, the eggs of H.contortus were observed in the feces of the infected Awassi sheep group at the four weeks after experimentally infection. While the eggs of F.gigantica was observed in feces at the fourteen weeks (after experimentally infection. The results revealed that body weight gain be significantly decreased specially between 10-15 weeks after injection at the level of (P<0.05) affected, while wool staple length was highly significant decrease at the level of (P<0.01) affected by infection with F.gigantica and H.contortus as compare with control group.
