Description
Summary:Coccidiosis, a parasitic infection caused by one or more of the numerous species of Eimeria is recognised as the disease that has severe economic impact on poultry production. In an experiment to determine the effect of vaccination on the infection with a Local isolate and Houghton strain of Eimeria tenella ( E. tenella ). Ninety (90) day-old Dominant black cockerel chicks of D109 strain were randomly divided into nine groups (A–I). Two commercially available anti-coccidial vaccines—Livacox ® (Biopharm, Czech Republic) and Immucox ® (Vetech, Ontario, Canada) were used to immunize the chicks. Immunization was done at 5 days-old by oral gavage and infection was carried out with 1.7 × 10 4 E. tenella of either Houghton strain or a field (Local) isolate at 4-weeks old. Six (6) days post-challenge, generalized pallor, moderate bloody diarrhea, slight reduction in feed intake and weight gain characterized the infected groups. There is a significant difference ( p
