Temporal gene expression profiles (clusters) based on the control studies. In each graph the x-axis depicts time in days, where ‘w’ stand for weaning and is illustrated by a vertical dotted line. The time period runs from day 0 (birth) to 35 days post–weaning. The y-axis denotes the (normalized) expression value, ranging from 5 to 11. The scale of both x- and y-axis are similar for each graph. Each graph represents one of the sixteen clusters, which are based on Self-Organizing Maps method
