Changes in antibody titres and comparative efficacy of some unconventional remedies in mitigating the effects of infectious bursal disease virus infection in pullet chicks

Unconventional remedies are used by farmers against infectious bursal disease (IBD). This study assessed changes in IBD antibody titres and efficacy of some unconventional IBD. Day old ISA brown pullets were assigned into eight groups (A-H) inoculated with a very virulent virus (vvIBDV) at 21 days age as follows; group A - administered aqueous leaf extract Kaya senegalensis (KS); B, C, D, E, F designated SEV, ENP, ASMS, DLP, OVX, respectively; G, H negative, positive control, respectively. Changes (Ab) titres, clinical signs, morbidity mortality rates, gross lesions, weights organ ratios (BF), spleen (S) thymus (T) assessed. There protective levels Ab chicks 2 7 age. SEV ASMS potentiated response to vvIBDV; mitigated the severity lesions body BF SBR; KS weight BBR; ENP rate, TBR; DLP OVX body, SBR. The demonstrated varied actions VVIBDV infection. leaves could be onset outbreak before vaccination. Processing reduce concentration antimetabolites is recommended.
