CL = continuous lighting (18 h of light [18L]:6 h of dark [6D]); IL = intermittent lighting (1L:3D:1L:3D:1L:3D:1L:3D:2L:6D); LP = lighting program; NS = not significant; T = time.

^{a, b, c, d, e, f, g} Means with different superscripts differ significantly (P < 0.0001).

Data were analysed using the fit model platform of JMP 8.0 (SAS Institute Inc. Cary, NC). When interactions were observed (P < 0.05), Tukey's honest significance test was used to compare treatment means. Values are means of 7 replicates (n = 7) for each treatment ± standard error.

Grey areas represent intervals when lights were off (scotoperiods).
