Fig 1. Mean bodyweight (± SE) of male broilers from d 1 after hatching to 42-d of age receiving from pens 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).

Weights were taken as pen weights and averaged over number of birds weighed.
