Abstract

This study aimed to identify hungry broiler breeders (n=12) preferences for quantitative (control) or qualitative dietary restriction (QDR) in a closed economy environment. The QDR option was either 3g calcium propionate/kg total feed (n=6) or 300g oat hulls/kg total feed (n=6). Quantitatively restricted or QDR portions ensured equal growth regardless of choice. Birds were separately taught a Control diet versus no food and a QDR diet versus no food task to allow each diet's satiating properties to be learnt. Birds had to associate the T-maze coloured arms with dietary outcomes to immediately obtain food. Birds learnt this task easily (p
