Abstract
This study investigated whether there is disturbance of calcium signal in the simulated salpingitis of laying hens. A total of 90 Roman Pink layers (81 wk; 1.916 � 0.17 kg) were divided into 3 groups (Control treated with PBS, 1.85 mg lipopolysaccharide (LPS)/layer as LPS group, 1.85 mg LPS/layer as LPS +organic chemical reagent (OCR) group) with 6 replicates of 5 layers.
