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

ABSTRACT

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
