Resumo: | This study was carried out to evaluate the effect of bee pollen (BP) levels on the IgG and IgM titers, weight of lymphoid organs, and on the tibia morphometric measures and mineralization in broilers at 21 and 42 days of age. Four hundred birds were used in an entirely randomized design with four treatments (0, 0.5, 1 and 1.5% of BP feed inclusion) and five replicates. At 21 and 42 days of rearing, blood samples were collected for IgG and IgM analysis, as well as lymphoid organs (bursa, thymus and spleen) and the tibiae. There was no effect (p&gt;0.05) of the BP inclusion on IgG titers, bursa and spleen weights, tibia morphometric measures and mineralization at 21 and 42 days, IgM titer at 42 days or thymus weight at 21 days. However, IgM titers at 21 days and the thymus weight at 42 days linearly increased with BP dietary inclusion. It was concluded that up to 1.5% BP can be included in broiler feeds until 21 days of age to enhance bird immunity.
