Effect of ascardia galli infestation on growth rate of local and foreign chicken breeds I. growth

One hundred and twenty chickens [60 Hypeco and 60 Fayoumi chicken] were studied in this experiment to observe the impact of Ascaridia galli infestation on some productive characters under Egyptian environmental conditions. The chickens used were experimentally infested with 300 embryonated Ascaridia galli eggs at ages of 15, 30 and 45 days old. Ascaridia galli was proved to affect growth rate, feed conversion and feed utilization. The economic evaluation of local and foreign poultry breeds in meat production and feed consumption indicated serious losses due to Ascaridia galli infestation in Hypeco and Fayoumi breeds

Effect of ascaridia galli infestation on local and foreign chicken breeds II physio-pathological status

One hundred and twenty Hypeco and Fayoumi chicken breeds were used in this experiment. Chickens were experimentally infected with embryonated Ascaridia galli at different ages and were slaughtered during the 2 phases of infection: Tissue phase, 20 days post infection and during the intestinal phase, 40 days post infection. The blood of each chicken was calculated and the macro- and microelements as well as the total protein, albumin and globulin were estimated. Physiological status was affected especially macro [inorganic phosphorus [Pi]] and microelements; zinc [Zn] concentration decreased significantly. Also, copper [Cu] was affected. Total plasma protein and globulin level increased significantly
