Both, CAV and limited floor space, can contribute to MD mortality. The latter by causing stress and the former by interfering with immune responses. I am not clear what you meant with"i did CAV vaccine right after 12 day clinical sign of CAV appear after 3week gradually it was diffuse and cause 2.5% mortality",Did you vaccinate at 12 days of age against CAV? And di you then get CAV lesions? if so ...

INTRODUCTION Although MD is in general well controlled by vaccination in ovo or at one d of age, MD remains a concern for several reasons. First of all, vaccination practices are often suboptimal resulting in some vaccine breaks. Proper use of standard operating procedures at the hatchery remains essential for optimal protection and has been the topic of many presentations. The short-term financi ...

Question 1: Only if the parent flock was vaccinated with HVT Question 2: The only antibodies in chickens are IgG (also called IgY), IgM and IgA. maternal antibodies are always IgG. Small amounts of IgA and IgM are present in the albumen and can be found in the newly hatched chicken, but these antibodies are of little relevance and not considered as maternal antibodies.

Dear Jwander Luka: Serotyping of MDV can be done by immunofluorescence or immunohistochemistry if you have the virus in cell culture using monoclonal antibodies. If DNA is available PCR can be used with serotype-specific primers. ELISA is used for serology to detect antibodies, but is in general not serotype specific. Matrenal antibodies will be present against serotype one by exposure to field s ...

No, the AGP and ELISA tests will cross react with antibodies generated by vaccine strains . Moreover, the presence of antibodies and even virus isolation does not necessarily indicate that there is an outbreak of MD
