Experiment 1 Live body weights (g) and relative weights (g/100 g live-weight) of internal organs of 8 wk old Hy-Line Brown layer strain pullets given a control diet^† (C) or a diet supplemented with 1%, insoluble fiber^† (IF) for 5 wk then either diet C or diet IF for a further 5 wk (Mean, pooled SEM).

^†Control diet - Ridley AgriProducts Pty Ltd., Pakenham, 3810, Australia, insoluble fiber – Arbocel RC Fine, JRS Co. Inc., Rosenberg, Germany.

^‡Weight ranges for Hy-Line Brown layer-strain, 13 wk 1126 – 1196g; 18 wk 1470 – 1570g (Hy-Line International, 2014) n = 6 (pen replicate) at 5 wk, n = 3 (pen replicate) at 10 wk.

*Means at 5 wk within the same row are significantly different (P < 0.05).

^a,bMeans at 10 wk within the same row with different superscript letters differ, P < 0.05.

¹C = control diet (no added IF) from 0 to 10 wk.

²IF = insoluble fiber (IF) diet containing 1% Arbocel RC Fine, from 0 to 10 wk.

³C-IF = control diet from 0 to 5 wk; IF diet from 5 to 10 wk.

⁴IF-CO = IF diet from 0 to 5 wk; diet C from 5 to 10 wk.
