Abstract

The loss due to disharmonized vaccination against infectious bursa disease (IBD) has necessitated the use of plant gums in poultry production. This study evaluated oral administration of IBD vaccine with equal proportions of Cedrella odorata and Khaya senegalensis in chickens. Two hundred and forty chicks of four groups; Mucilages-IBD Vaccine (virus challenged) (GGVOR), IBD Vaccine alone (virus challenged) (GVOR), Mucilage alone (virus challenged) (GOR), and Not Vaccinated-No mucilae (virus challenged) (NVNG/C). The birds were monitored clinically post vaccination and infection; lymphoid tissues were taken from weak euthanized birds for gross and microscopic examination. The clinical data and lesion scores from the tissues were analysed and compared at α=0.05. All the birds were apparently healthy pre and post vaccinations. A few days post infection there were signs of pecking, soiling of the vents and feathers with projectile yellowish diarrhoea and varied mortalities in the GOR and NVNG/G birds. The bursa of Fabricius, spleen, caecal tonsil and Harderian gland were oedematous, hyperplastic, haemorrhagic and inflamed to various degree across the groups but very severe in NVNG/C birds. No mortality was recorded in GVVOR and GVOR. Administration of IBDV vaccines with Cedrella odorata and Khaya senegalensis gums clinically enhanced the birds against IBD.
