The objective of this study was to determine the effect of different levels of dietary @entity1853 on selected immune parameters of young @entity233 . A total of 357 one-day-old female Hybrid Converter @entity233 were randomly divided into three groups with low, medium and high level of dietary me- @entity32341 (LM, MM, HM) of seven replicates each. @entity1853 was added to the basal diet (LM) at 0.16% (MM) and 0.32% (HM). At 17 days of age, seven birds per group were vaccinated against @entity281 , with ORNITIN (ABIC) vaccine. At 28 days of age, blood was sampled and the birds were euthanized. The serum concentrations and activity of selected biochemical parameters, total IgY and IgM, and vaccine-induced antibody titers (IgY) against ORT were determined. The percentages of @entity71492 +, @entity71493 +, @entity71492 +/ @entity71493 + T cell subpopulations and IgM+ B cell subpopulation were determined in blood and organs by flow cytometry. Different supplementary levels of @entity1853 had no significant effect on vaccine-induced anti- body titers against ORT or total serum IgM and IgY levels, as well as on the percentages of periph- eral blood T and B cell subsets. Increasing dietary @entity1853 rates decreased the percentage of @entity71492 + T cell subpopulation, however it has increased the percentage of IgM+ B cell subpopulation in the spleen. Vaccination against ORT resulted in a significant decrease in the percentage of @entity71492 + T cell subset and an increase in the percentage of @entity71493 + T cell subset in the spleen. It could be concluded that MM @entity233 have developed the most desirable values of immune parameters.
