The purpose of this study was to investigate if the tecnology of rearing system can influence the fear of Grey Prtridge chicks. Fear was measured in artificially reared chicks, laid-incubated then reared by parents chiks, and forcedly adopted by broody hens chiks. Results showed that, tonic immobility test, novel object test and metronome test can differentiate the rearing technologies while box plus experiment test, and box emergence test did not reach the m.d.s. between rearing systems.

Abstract
The purpose of this study was to investigate if the tecnology of rearing system can influence the fear of Grey Prtridge chicks. Fear was measured in artificially reared chicks, laid-incubated then reared by parents chiks, and forcedly adopted by broody hens chiks. Results showed that, tonic immobility test, novel object test and metronome test can differentiate the rearing technologies while box plus experiment test, and box emergence test did not reach the m.d.s. between rearing systems.File in questo prodotto:
