Studies on the effect of specific immunostimulant on the immune response of chickens I Evaluation of the immunopotentiates of New Castle Disease virus-specific transfer factor [NDV-S-TF] in chicken

ABSTRACT

Efficacy of the administration of Newcastle 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 blastogenesis 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 showed good protection percentage than non-immunized birds
