Fig 2. Mean water consumption (± SE) of broiler pens receiving either no silicon supplementation (control, C, n = 5), normal supplementation (0.011 ml supplement/kg BW, normal, N, n = 5), or high supplementation (0.063 ml supplement/kg BW, High, H, n = 5).

Supplementation tended to increase water consumption (P = 0.07). *Indicates difference between treatment groups (N and H) and control (C, P < 0.005).
