Can conditioned place preference be used to determine hungry broiler preferences for qualitative or quantitative dietary restriction?

Study which using conditioned place preference to investigate broiler breeders preferences for qualitative or quanititive feed restriction.

Year of Publication2011

Chronic hunger is a welfare issue for quantitatively feed restricted broiler breeders. It is not clear if qualitative feed restriction reduces hunger, thus novel methods are needed to investigate this. Conditioned Place Preference (CPP) is used to determine treatment-induced positive affective states by pairing an environment with the ‘affect’ caused by (usually) drug administration. Using CPP, Dixon et al., (in prep) found that broiler breeders preferred an environment associated with larger feed portions. Therefore, CPP might allow identification of the satiating effects of qualitative feed restriction. This study used a CPP paradigm to investigate broiler (as a model for broiler breeder) preferences for a diet containing the appetite suppressant Calcium Propionate (CAP) over quantitative feed restriction (QFR). To validate this approach, a second (control) group of birds were tested using environments associated with QFR and ad libitum (AL) feeding.
