The handling and transport of broilers and spent hens

Abstract

The effects of handling and transportation on spent hens and broilers are presented and discussed with particular reference to measures of the welfare of the birds. Points in the handling and transport process where improvements are required are outlined. The procedures used to handle and transport spent hens and broilers result in welfare problems for the birds which are often very severe. There is evidence for substantial emergency responses, such as adrenal cortex activity. There can also be birds dead on arrival at the slaughterhouse, bruising, and high incidences of bone breakage. Housing hens in battery cages for long periods results in bone fragility. The greatest welfare problem is the normal rough handling which leads to poorer welfare than does a short vehicle journey. Better handling procedures are essential. Poor conditions on the journey also result in poor welfare. Much research is needed using a wide range of indicators to assess welfare and to design housing systems, handling methods, and transport procedures which do not result in poor welfare.
