Description
Summary:The investigations are based on determining the influence of intestinal microflora variation on the level of postvaccination antibody titers against Newcastle disease. Thus, several chicken groups were vaccinated and implicitly, there were taken samples for making subsequent serological tests in order to determine the antibody titers and also intestinal lavages to determine microflora. As a result, it was determined that the variation of qualitative intestinal microflora is insignificant and the level of maternal antibody titers against Newcastle disease, at the age of one day, is quite high and it is able to protect chickens up to the age of 15-20 days, when the first vaccination is recommended. Rezumat. Investigaţiile se bazează pe determinarea influenţei variaţiei microflorei intestinale asupra nivelului titrelor de anticorpi postvaccinali împotriva bolii Newcastle. Astfel, mai multe loturi de pui au fost supuse vaccinării, implicit s-au recoltat probe pentru testele serologice ulterioare de determinare a titrelor de anticorpi şi lavaje prelevate de la nivel intestinal, pentru determinarea microflorei. S-a stabilit că variaţia microflorei intestinale calitativă este nesemnificativă şi că nivelul titrelor de anticorpi maternali contra pseudopestei aviare, la vârsta de o zi, este destul de mare, capabil să protejeze puii de găină până la o vârstă de aproximativ 15-20 de zile, atunci când se recomandă prima vaccinare la pui.
