Research has uncovered much about how welfare impacts broilers’ physical and functional traits, but less is known about their mental state. A doctoral student at Virginia Tech studied fear and anxiety in fast- and slow-growing broilers, as well as the impact of environmental complexities.
A North Carolina State University study, led by graduate student Athena He-DeMontaron, compared the growth performance and mortalities of fast- and slow-growing strains of broilers reared in silvopastures, which provide a natural habitat with trees, shrubbery and vegetation and indoor facilities. How did these systems impact the different bird strains?
As poultry companies weigh cost and efficiency with higher animal welfare standards, research comparing conventional and slow-growing broiler breeds showed that the slow-growing chickens displayed behaviors more closely associated with positive welfare.
