Abstract

Seric Antibody and Anemia detection in broiler to AIA in Mara and La Canada de Urdaneta Farms of the Zulia State. One hundred and forty vine broiler from Mara and La Canada de Urdaneta commercial farms of the Zulia State were tested for presence of avian anemia infection (A.I.A) serum antibodies and anemia as a clinical sign of disease. From these serums, 68.5% (102/149) showed a antibodies title ≥ 4 (1:16 dilution) to ELISA test which is considered positive for it. The 87.2% positive sera belong to chickens between 6 and 14 days of age. Microhematocrit technique showed that only 13.4% (20/149) of tested birds had anemia (hematocrits < 27%). From these 90% (18/20) had antibodies against A.I.A and 6 to 14 days of age. All these factors permit to think of clinical disease is present in the birds. A highly significant negative correlation (r < 0.5; P ≤ 0.05) between age and presence of antibodies against A.I.A was found in the birds under testing which shows chicken sensitivity t...
