An experimental study was carried out to evaluate a new simple method for massive production of bluetongue virus (BTV) specific antibodies by specific IgY extraction from the egg yolk of immunized hens with BTV polyvalent vaccine. After detection of the development of the serum precipitating antibodies, serum samples and egg batches were collected from the immunized hens at regular intervals then titrated by the indirect ELISA. The serum antibody titres were compared with the extracted egg yolk IgY antibody titres during the period of the study which elapsed 21 weeks and during this period 3 doses were injected. The results revealed that the egg BTV specific antibody titres were nearly similar to the serum antibody titres providing a higher yield of specific antibodies can be collected from the immunized hens depending on the availability egg production and occasional posturing. The diagnostic efficiency of the prepared egg yolk antibodies was also proved by successful detection of 13 BTV isolates using it in the procedures of indirect fluorescence antibody technique.
