The impact of phenotypic appearance on body weight and egg production in laying hens: a group-size- and experience-dependent phenomenon.

Poultry science - 1 Jul 2014

Marin R H, Liste M G, Campderrich I, Estevez I

Abstract excerpt

Alterations of birds' phenotypic appearance (PA) may lead to unwanted behaviors, potentially impairing poultry welfare, health, and productive performance. Likewise, group size may play an important role modulating the expression of adaptive behaviors. This study evaluates whether changes in the PA of Hy-line Brown laying hens may affect their BW and egg production, and if so, whether these effects depend on...
