Validation of tests for on-farm assessment of the hen–human relationship in non-cage systems
The relationship of laying hens towards humans is an important aspect of animal welfare. Tests for assessing the hen–human relationship on farm should be validated prior to their use. In this paper, we investigated the validity of three recently developed tests assumed to measure the hen–human relationship in non-caged hens. The study was conducted in […]
Development of on-farm methods to assess the animal-human relationship in laying hens kept in non-cage systems
The aim of this study was to develop a set of tests to assess the reaction of laying hens towards humans in non-cage systems and to investigate the repeatability within and between days. Based on a literature survey six tests were developed or modified, which were examined for practicability and adapted in a first phase. […]
