From: Development of vaccine-induced immunity against TRT in turkeys depends remarkably on the level of maternal antibodies and the age of birds on the day of vaccination

  1. aIn all experiments vaccinated birds were inoculated oculonassaly with 104 TCID50 of live attenuated aMPV/A vaccine.
  2. b10 samples of undiluted tracheal washings per group were analyzed.
