Abstract

Efficacy of the administration of new castle disease Virus-Specific-Transfer factor (NDV-S.TF) either orally or intramuscular injection in chickens was evaluated. The results revealed that NDV-S-TF potentiated the lymphocyte blastogensis response against PHA mitogen and NDV antigen; as well as induced extraordinary potentiation of the haemagglutinating antibody production against NDV in treated chickens than non-treated one. Chickens immunized with NDV-S-TF and challenged were showed good protection percentage then non-immunized birds.
