Abstract

CHICKEN INFECTIOUS ANEMIA (CIA), a disease of young chickens, can be prevented by immunization of breeding flocks with LIVE VACCINEs. The objective of the present work was to perform the efficacy of one attenuated LIVE VACCINE Nobilis CAV P4 (Intervet Co., Netherland) based on induction of persistent antibodies in broiler breeder and their progenies compared to unvaccinated BROILER BREEDER FLOCK. The vaccine administrated to Ross 308 BROILER BREEDER FLOCKs at 6-week old via S.C. rout. A total of 352 serum samples were collected from vaccinated and unvaccinated breeder flocks from 6 to 33 week old (5, 12, 16, 20 and 28 weeks after vaccination) and twice in their progeny flocks at one- day old. Sera were analyzed by indirect ELISA (Synbiotics Corporation, USA) and data were compared statistically between the two groups by t-test. The results showed natural infection of CIA virus in unvaccinated breeder flock and not only the mean titer was higher but also thecoefficient variant (CV%) was lower than vaccinated breeder flock significantly (P<0.05). But the CV% in progeny of vaccinated breeder flock was lower than the CV% in progeny of unvaccinated breeder flock. Also, there was anti-CAV antibody negative in hens and progenies in unvaccinated breeder flock, so these hens potentially can transmit the virus vertically. All breeders from vaccinated flock were positive serologically. It seemed that vaccination could be an efficient rout for eliminating susceptible birds, decreasing variation in anti-CAV antibodies titers and induction persistent antibody titer. However more experiments need to be carried out to define if vaccination really is desirable.
