Proliferation of peripheral blood mononuclear cells (PBMCs) and lysozyme activity of sera. A. PBMCs were separated from the vaccinated cattle that were fed with the germanium biotite supplement or without the supplement at 0 and 23 weeks. The proliferation of the PBMCs was estimated after stimulation with LPS or ConA. B. The lysozyme activities of the sera from the vaccinated cattle that were fed with the germanium biotite supplement or without the supplement were measured based on the dissolution ability against Micrococcus lysodeikticus.
