Figure 3From: The effects of zinc amino acid complex supplementation on the porcine host response to Lawsonia intracellularis infectionEvaluation of serum antibody responses in animals. At 14, 21 and 28 dpi, the IPMA assay was used to quantify L. intracellularis specific antibodies in serum of animals. A Percent of animals with antibodies in serum against L. intracellularis. B IPMA titer per treatment at different timepoints post-infection. Different letters indicate statistical significance (p < 0.05), error bars represent the standard error. No significant differences were found in IPMA titers between treatments but only between time points (p < 0.05).Back to article page
