Abstract
Heterophil (H) to lymphocyte (L) ratios and durations of tonic immobility (TI) were measured to assess stress and fear responses, respectively, in broiler chickens provided either 12 h of natural lighting (12L) or 12 h natural lighting and 12 h of supplementary lighting (24L). Birds illuminated 24L had greater H/L ratios and TI durations than their 12L counterparts. Neither age, sex nor cage level had significant effect on TI reactions.
