Rate of Transfer of Infectious Anaemia Maternal Antibodies from Broiler Breeders To the Progeny: a Field Evaluation

Clinical manifestation of the disease caused by chicken anaemia virus (CAV) occurs when chicks are vertically contaminated or before second week life. CAV control is based on vaccination broiler breeders in order to promote progeny protection through maternal antibodies. This work aims evaluate, under field conditions, antibody title commercial at 28, 48, and 68 weeks age, rate transference progeny, as well duration antibodies up 21 days age. Thus, a total 92 sera samples from 93,000 vaccinated with live vaccine for 14 age 366 their respective were analyzed using ELISA. Breeders’ ranged between 5051 8660, these titles may provide sufficient progeny. On average, 63% transferred lasted chick’s It possible conclude that procedure used this company against seems be effective inducing high levels transfering protective
