| dc.description.abstract | The dissertation presents the results of three studies conducted on intensively reared turkey
flocks. The first research aimed to determine the association between biosecurity and animal
welfare measures in large-scale fattening turkey farms in Hungary. Large-scale farms raising male
fattening turkeys across Hungary were contacted, with 24 agreeing to participate. The
Biocheck.UGent questionnaire was used to evaluate biosecurity measures, and Animal Welfare
Indicators (AWIN) protocol was used for welfare assessment. The association between
biosecurity and welfare indicators was investigated by correlation testing and prediction accuracy
using random forest classification. The areas of biosecurity that were shown to be closely linked
to the welfare index were the organization of the farm (farm management, supply of materials),
the control and hygienic measures implemented between farm structures, cleaning and
disinfection measures on the farm, and control and hygienic measures implemented in the case
of farm workers and visitors upon entrance and exit. The study highlighted the link between
biosecurity and animal welfare in turkey production, concluding that enhanced biosecurity
measures correlate with better welfare outcomes and emphasizing the need for comprehensive
and well-implemented biosecurity protocols. | en_US |
