Development of decision support tool for minimising feather and vent pecking

Feather and vent pecking in laying hens still impose a widespread threat to the welfare of the birds and therefore more knowledge on the relative importance of different risk factors for feather and vent pecking, particular during the likely most important rearing period, is needed. Aim of the study is to develop a decision support tool for minimising feather and vent pecking in laying hens kept in non-cage systems. A theoretical model of risk factors for feather and vent pecking based on literature and expert opinion has been developed. To test the model 50 data sets, each consisting of data from one rearing and two subsequent laying units, will be analysed by using advanced multivariate statistics. Data comprises bodily state and mortality of hens, results from farmer-interviews and parameters recorded from the husbandry system.
