Effect of genetics, vaccine dosage, and postvaccination sampling interval on early antibody response to Salmonella enteritidis vaccine in broiler breeder chicks

Broiler breeder chicks of two different genetic lines were evaluated for early antibody response to Salmonella enteritidis (SE) vaccine. Antibody responses to three dosages of SE vaccine administered at 22 d of age were measured at 3, 6, and 10 d postvaccination. Within each line, antibody levels at...

Description
Summary:Broiler breeder chicks of two different genetic lines were evaluated for early antibody response to Salmonella enteritidis (SE) vaccine. Antibody responses to three dosages of SE vaccine administered at 22 d of age were measured at 3, 6, and 10 d postvaccination. Within each line, antibody levels at 10 d postvaccination were significantly higher than at either 3 or 6 d postvaccination. At all vaccine dosages, there was a significant antibody-response difference between the genetic lines at 6 and 10 d postvaccination. The vaccine dosage significantly affected antibody levels in one of the two genetic lines. These results demonstrate a genetic component of early antibody response to SE vaccine in broiler breeder chicks.
